Accelerometers, Gyros, and Temperature Sensors February 2010 The
ADXL312 low-power, digital-output,
3-axis Accelerometer measures dynamic acceleration (motion, shock, and
vibration) and static acceleration (tilt and gravity) over a user-selectable
±1.5-/±3-/±6-/±12-g range, with 10-/11-/12-/13-bit max resolution, 0.5%
nonlinearity, and 0.01%/°C temperature stability. Output data rates from 6.25 Hz
to 3200 Hz can be selected to suit the application. Special built-in
motion-detection functions—including activity-, tap-, and free-fall sensing—can
be mapped to interrupt-output pins. A 32-level FIFO minimizes host processor
intervention. Data is available via SPI- and I2C-compatible serial
interfaces. Housed in a small, low-profile, 5-mm × 5-mm × The ADXRS652 Yaw-Rate Gyroscope uses surface micromachining—the same process used to make high-volume, high-reliability accelerometers—to produce a low-cost, functionally complete angular-rate sensor—and integrates it with all of the signal-conditioning electronics required to produce a stable output voltage proportional to the angular rate about the Z-axis. The output is ratiometric to an external reference, with 7-mV/°/s sensitivity over a ±250°/s measurement range (5-V reference). Bandwidths from 0.01 Hz to 2500 Hz can be established by an external capacitor. The temperature output allows the sensor to be calibrated over temperature, and the device’s self-test inputs provide electromechanical excitation to test for proper operation of the sensor and signal-conditioning circuits. Designed for industrial applications, inertial measurement units, and platform stabilization, the device can survive 2000-g powered shocks.

It provides 14-bit digital data proportional to the angular rate about—and the acceleration along—the X-, Y-, and Z-axes—and 12-bit digital data proportional to the on-chip temperature, power-supply voltage, and voltage on an auxiliary analog input. An auxiliary DAC provides an analog output with 12-bit resolution and a 3.3-V full-scale range. The device is fully calibrated for sensitivity, bias, axial alignment, and linear acceleration; and dynamically compensated from –40°C to +85°C.

The device can store 1K samples using automatic, manual, or event-capture data collection modes. It also measures temperature and supply voltage, captures peaks, and provides a condition-based alarm function. The ADIS16260 and ADIS16265 iSensor® Angular-Rate Measurement Systems combine an iMEMS® yaw-rate gyroscope with embedded signal processing to provide a compact, factory-calibrated, tunable digital sensor with an SPI-compatible output. Sampling at up to 2.048 ksps, it measures angular rate about the Z-axis—with ±80°/s, ±160°/s, ±320°/s range settings—as well as temperature, supply voltage, and the voltage on an auxiliary input. It also includes an auxiliary DAC, digital self test, and configurable alarms. May 2009 The

Using patented iCoupler® technology, they combine high-speed CMOS with integrated micro-transformers, eliminating the uncertain current-transfer ratios, nonlinear transfer functions, and drift (with time and temperature) associated with optocouplers. Power consumption is as much as 90% less, and no external drivers or discrete devices are required. Providing 1-kV isolation, they meet UL and CSA safety- and regulatory requirements. Featuring 3-ns pulse-width distortion, 6-ns channel-to-channel mismatch, and 15-kV/μs common-mode transient immunity, A-, B-, and C-grades operate at data rates from dc to 1 Mbps, 10 Mbps, and 25 Mbps, respectively. The power supplies on each side can range from 3 V to 5.5 V, allowing level-translation across the isolation barrier. Refresh circuitry ensures correct output data levels in the absence of input transitions—and during power-up and power-down conditions. The ADuM7440 has four channels that communicate in the same direction; the ADuM7441 has one channel that communicates in one direction and three that communicate in the reverse direction; and the ADuM7442 has two channels that communicate in one direction and two that communicate in the reverse direction. June 2009 The ADuM4160 iCoupler® Digital Isolator combines high-speed CMOS and micro-transformers to provide bidirectional isolation for full- (12 Mbps) and low- (1.5 Mbps) speed USB ports. Directly inserted in the D+/D– lines, it determines data direction on a packet-by-packet basis. A robust device, it provides short-circuit protection, 5-kV rms isolation, 25-kV/μs common-mode transient immunity, and enhanced system-level ESD performance. The propagation delay is comparable to that of a standard hub and cable. April 2009 The ADM2582E/ADM2587E Isolated RS-485 Transceivers employ iCoupler® and isoPower™ technologies to integrate a 3-channel isolator, a 3-state differential line driver, a differential-input line receiver, and an isolated dc-to-dc converter. Operating at data rates up to 16 Mbps/500 kbps, they enable full- or half-duplex data communication over multipoint-bus transmission lines. Designed for balanced transmission, they comply with ANSI/TIA/EIA RS-485 and ISO 8482 standards. The line inputs and outputs provide ±15-kV ESD protection, 25-kV/μs transient immunity, and 2500-V rms isolation, making the devices suitable for operation in electrically harsh environments.

August 2009 The ADM6326, ADM6328, ADM6346, and ADM6348 ultralow-power Microprocessor Reset circuits monitor the supply voltage in microprocessor-based systems—and provide an active-low reset signal during power-up, power-down, and brownout conditions. With 24 reset threshold voltage options, from 2.2 V to 4.63 V, they are ideal for monitoring supplies from 2.5 V to 5 V. An internal timer maintains the reset condition for at least 100 ms, allowing the power supply a chance to stabilize. The ADM6326 and ADM6346 have push-pull outputs; the ADM6328 and ADM6348 have open-drain outputs. The ADM6326 and ADM6328 guarantee a 1-μA maximum supply current. The ADM12914 four-channel Voltage Supervisor monitors four power supplies and provides an active-low, open-drain alert signal when any of them experiences an under- or over-voltage condition. A high-precision version of the ADM2914, it features an industry-leading threshold accuracy of ±0.8% max over the –40°C to +125°C temperature range. Two of the four inputs monitor positive supplies; the other two inputs can be independently configured to monitor either positive- or negative supplies. The fault outputs are immune to power supply glitches; and an adjustable delay allows the supplies to stabilize after all faults have cleared. An input-supply shunt regulator enables the device to be run off of higher-voltage supplies. Two different versions are available: the -1 includes a latch function, while the -2 includes a disable function. The
