Additional Details
The ADPD4100/ADPD4101 operate as a complete multimodal sensor front end, stimulating up to eight light emitting diodes (LEDs) and measuring the return signal on up to eight separate current inputs. Twelve time slots are available, enabling 12 separate measurements per sampling period.
The data output and functional configuration utilize an I2C interface on the ADPD4101 or a serial port interface (SPI) on the ADPD4100. The control circuitry includes flexible LED signaling and synchronous detection. The devices use a 1.8 V analog core and 1.8 V/3.3 V compatible digital input/output (I/O).
The analog front end (AFE) rejects signal offsets and corruption from asynchronous modulated interference, typically from ambient light, eliminating the need for optical filters or externally controlled dc cancellation circuitry. Multiple operating modes are provided, enabling the ADPD4100/ADPD4101 to be a sensor hub for synchronous measurements of photodiodes, biopotential electrodes, resistance, capacitance, and temperature sensors. The multiple operation modes accommodate various sensor measurements, including, but not limited to, photoplethysmography (PPG), electrocardiography (ECG), electrodermal activity (EDA), impedance, capacitance, temperature, gas detection, smoke detection, and aerosol detection for various healthcare, industrial, and consumer applications.
The ADPD4100/ADPD4101 are available in a 3.11 mm × 2.14 mm, 0.4 mm pitch, 33-ball WLCSP and 35-ball WLCSP
Applications
- Wearable health and fitness monitors: heart rate monitors (HRMs), heart rate variability (HRV), stress, blood pressure estimation, SpO2, hydration, body composition
- Industrial monitoring: CO, CO2, smoke, and aerosol detection
- Home patient monitoring

EVAL-ADPD4100-4101
ADPD4100/ADPD4101 Evaluation Board
Product Detail
The EVAL-ADPD4100Z-PPG evaluation board provides users with a simple means of evaluating the ADPD4100/ADPD4101 photometric front end.
The EVAL-ADPD4100Z-PPG evaluation board implements a simple discrete optical design for vital signs monitoring applications, specifically wrist-based photoplethysmography (PPG).
The EVAL-ADPD4100Z-PPG has three green light emitting diodes (LEDs), one infrared (IR), and one red LED, all separately driven. A single 7 mm2 photodiode (PD) is populated on the board. The PD has no optical filter coating. However, a pin for pin alternative device with an IR block filter is available.
The full evaluation system includes the Wavetool Evaluation Software graphical user interface (GUI) that provides users with low level register access and high level system configurability. Raw data streamed to this tool can be displayed in real time with limited latency. Views are provided for both frequency and time domain analysis.
A user datagram protocol (UDP) transfer capability from the Wavetool Evaluation Software (available for download on the EVAL-ADPD4100Z-PPG product page) allows data stream connections and register configurability to external analysis programs, such as LabVIEW® or MATLAB®, in real time.
The EVAL-ADPD4100Z-PPG board is powered by the EVAL-ADPDUCZ microcontroller board (obtained from the EVAL-ADPD4100Z-PPG product page). In addition to the power requirements, serial port interface (SPI) (default) or I2 C data streams are received from the ADPD4100 by the microcontroller. A ribbon cable connects the two boards. The microcontroller repackages the data, sending it to a virtual serial port over the USB to the PC, displayed on the Wavetool Evaluation Software. The EVAL-ADPD4100Z-PPG can also be connected directly to the microcontroller development system of the user, using the SPI for the ADPD4100 (or I2C for the ADPD4101).
The ADPD4100/ADPD4101 data sheet, available at www.analog.com, provides full specifications for the ADPD4100/ADPD4101. Consult the ADPD4100/ADPD4101 data sheet in conjunction with this user guide when using the EVAL-ADPD4100Z-PPG.

EVAL-HCRWATCH4Z
Vital Signs Monitoring (VSM) Watch
Product Detail
The vital signs monitoring (VSM) watch, EVAL-HCRWATCH4Z, is a modular development, demonstration, and data collection platform for high performance vital signs monitoring applications based on Analog Devices, Inc., analog front ends (AFEs) and sensors.
The VSM watch is a wearable, battery-powered device that enables the continuous monitoring and on-demand spot check measurement of photoplethysmography (PPG), electrodermal activity (EDA, bioimpedance-based), skin temperature, electrocardiography (ECG, biopotential based), and motion/activity (based on a 3‑axis accelerometer).
The VSM watch allows synchronized, multiparameter data storage on internal memory for later data retrieval and offline analysis and/or live monitoring on a PC (Windows® OS) or Android- or iOS-based device.

EVAL-ADPD410x-ARDZ
ADPD4100/ADPD4101 Arduino Shields
Product Detail
EVAL-ADPD4100-ARDZ and EVAL-ADPD4101-ARDZ are simple, Arduino form-factor breakout board for developing ADPD4100 and ADPD4101 applications, respectively. The ADPD4101, interfaced through I2C, and the ADPD4100, interfaced through SPI, are highly versatile, multimodal sensor front ends, stimulating up to eight light emitting diodes (LEDs) and measuring the return signal on up to eight separate current inputs.
There are a number of other evaluation platforms for these devices, including the EVAL-ADPD4100Z-PPG, optimized for photoplethysmograph applications, and the reference design CN0503, optimized for optical liquid analysis applications (colorimetry, turbidity, fluorescence). The EVAL-ADPD410X-ARDZ boards come in handy for adapting these evaluation boards to meet specific application requirements, as well as for "ground up" development of new applications.
