The ADPD105/ADPD106/ADPD107 are highly efficient, photometric front ends, each with an integrated 14-bit analog-to-digital converter (ADC) and a 20-bit burst accumulator that works with flexible light emitting diode (LED) drivers. The accumulator is designed to stimulate an LED and measure the corresponding optical return signal. The data output and functional configuration occur over a 1.8 V I²C interface on the ADPD105 or SPI on the ADPD106 and ADPD107. The control circuitry includes flexible LED signaling and synchronous detection.

The analog front end (AFE) features best-in-class rejection of signal offset and corruption due to modulated interference commonly caused by ambient light.

Couple the ADPD105/ADPD106/ADPD107 with a low capacitance photodiode of <100 pF for optimal performance. The ADPD105/ADPD106/ADPD107 can be used with any LED. The ADPD105 is available in a 2.46 mm × 1.4 mm WLCSP and a 4 mm × 4 mm LFCSP. The SPI only versions, ADPD106 and ADPD107, are available in a 2.46 mm × 1.4 mm WLCSP.

• Wearable health and fitness monitors
• Clinical measurements, for example, SpO₂
• Industrial monitoring

The ADF7030 is a low power, high performance, integrated radio transceiver supporting narrowband operation in the 169.4MHz to 169.6MHz ISM bands. The ADF7030 supports transmit and receive operation at 2.4kbps and 4.8kbps using 2GFSK modulation and transmit operation at 6.4kbps using 4GFSK modulation.

The ADF7030 features an on-chip ARM® Cortex®-M0 processor that performs radio control and packet management.

• Wireless M-Bus Mode N (EN 13757-4)
• Smart metering
• Social alarms
• Active tag asset tracking

The ADF7030-1 is a fully integrated, radio transceiver achieving high performance at very low power. The ADF7030-1 is ideally suited for applications that require long range, network robustness, and long battery life. It is suitable for applications that operate in the ISM, SRD, and licensed frequency bands at 169.4 MHz to 169.6 MHz, 426 MHz to 470 MHz, and 863 MHz to 960 MHz. It provides extensive support for standards-based protocols like IEEE802.15.4g while also providing flexibility to support a wide range of proprietary protocols.

The highly configurable low intermediate frequency (IF) receiver supports a large range of receiver channel bandwidths from 2.6 kHz to 738 kHz. This range of receiver channel bandwidths allows the ADF7030-1 to support ultranarrow-band, narrowband, and wideband channel spacing.

The ADF7030-1 features two independent PAs supporting output power ranges of −20 dBm to +13 dBm and −20 dBm to +17 dBm. The PAs support ultrafine adjustment of the power with a step resolution of 0.1 dB. The PA output power is exceptionally robust over temperature and voltage. The PAs have an automatic power ramp control to limit spectral splatter to meet regulatory standards.

The ADF7030-1 features an on-chip ARM^® Cortex^®-M0 processor that performs radio control, radio calibration, and packet management. Cortex-M0 eases the processing burden of the host processor because the ADF7030-1 integrates the lower layers of a typical communication protocol stack. This internal processor also permits the download and execution of Analog Devices, Inc., provided firmware modules that can extend the functionality of the ADF7030-1.

The ADF7030-1 has two packet modes: generic packet mode and IEEE802.15.4g mode. In generic packet mode, the packet format is highly flexible and fully programmable, thereby ensuring its compatibility with proprietary packet formats. In IEEE802.15.4g packet mode, the packet format conforms to the IEEE802.15.4g standard. FEC, as per the IEEE802.15.4g standard, is also supported.

The ADF7030-1 operates with a power supply range of 2.2 V to 3.6 V and has very low power consumption in both Tx and Rx modes, enabling long lifetimes in battery-operated systems. An ultralow power deep sleep mode achieves a typical current of 10 nA with the configuration memory retained.

The ADF7030-1 supports smart wake mode (SWM) where the ADF7030-1 can wake up autonomously from sleep using an internal real-time clock (RTC) without intervention from the host processor. After wake-up, the ADF7030-1 operates autonomously. This functionality allows carrier sense, packet sniffing, and packet reception while the host processor is in sleep mode, thereby reducing overall system current consumption. The ADF7030-1 autonomous operation can also be triggered by the host processor using the interrupt input of the ADF7030-1.

A complete wireless solution can be built using a small number of external discrete components and a host processor (typically a microcontroller). The host processor can configure the ADF7030-1 using a simple command-based protocol over a standard 4-wire SPI interface. A single-byte command transitions the radio between states or performs a radio function.

The ADF7030-1 is available in two package types: a 6 mm × 6 mm, 40-lead LFCSP and a 7 mm × 7 mm, 48-lead LQFP. Both package types use NiPdAu plating to mitigate against silver migration in high humidity applications. The ADF7030-1 operating temperature range is −40°C to +85°C.

There is an ADXL362 variant called ADXL362-MI which is applicable to medical implantable and other Class III devices. The ADXL362 is an ultralow power, 3-axis MEMS accelerometer that consumes less than 2 µA at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL362 does not alias input signals by undersampling; it samples the full bandwidth of the sensor at all data rates.

The ADXL362 always provides 12-bit output resolution; 8-bit formatted data is also provided for more efficient single-byte transfers when a lower resolution is sufficient. Measurement ranges of ±2 g, ±4 g, and ±8 g are available, with a resolution of 1 mg/LSB on the ±2 g range. For applications where a noise level lower than the normal 550 µg/√Hz of the ADXL362 is desired, either of two lower noise modes (down to 175 µg/√Hz typical) can be selected at minimal increase in supply current.

In addition to its ultralow power consumption, the ADXL362 has many features to enable true system level power reduction. It includes a deep multimode output FIFO, a built-in micropower temperature sensor, and several activity detection modes including adjustable threshold sleep and wake-up operation that can run as low as 270 nA at a 6 Hz (approximate) measurement rate. A pin output is provided to directly control an external switch when activity is detected, if desired. In addition, the ADXL362 has provisions for external control of sampling time and/or an external clock.

The ADXL362 operates on a wide 1.6 V to 3.5 V supply range, and can interface, if necessary, to a host operating on a separate, lower supply voltage. The ADXL362 is available in a 3 mm × 3.25 mm × 1.06 mm package.

Refer to the ADXL362-MI data sheet for information on ADXL362-MI. The ADXL362-MI is processed through a special, high reliability manufacturing flow involving additional process, test, and quality controls to meet the quality and reliability requirements of implantable and other Class III medical devices.

The ADP5301 is a high efficiency, ultralow quiescent current step-down regulator that draws only a 180 nA quiescent current to regulate the output at no load.

The ADP5301 runs from an input startup voltage range of 2.15 V to 6.50 V, allowing the use of multiple alkaline/NiMH, Li-Ion cells, or other power sources. The output voltage is selectable from 0.8 V to 5.0 V by an external VID resistor and factory fuse. The total solution requires only four tiny external components.

The ADP5301 can operate between hysteresis mode and PWM mode via the SYNC/MODE pin. The regulator in hysteresis mode achieves excellent efficiency at a power of less than 1 mW and provides up to 50 mA of output current. The regulator in PWM mode produces a lower output ripple and supplies up to 500 mA of output current. The flexible configuration capability during operation of the device enables very efficient power management to meet both the longest battery life and low system noise requirements.

The ADP5301 contains a VOUTOK flag, which monitors the output voltage and runs at a 2 MHz switching frequency in PWM mode. SYNC/MODE can synchronize to an external clock from 1.5 MHz to 2.5 MHz.

Other key features in the ADP5301 include separate enabling, quick output discharge (QOD), and safety features such as overcurrent protection (OCP), thermal shutdown (TSD), and input undervoltage lockout (UVLO).

The ADP5301 is available in a 9-ball, 1.65 mm × 1.87 mm WLCSP rated for a −40°C to +125°C junction temperature range.
