Multimodal sensor front end

25 November 2020 Analogue, Mixed Signal, LSI

Analog Devices' ADPD4000 and ADPD4001 operate as a complete multimodal sensor front end by stimulating up to eight LEDs and measuring the return signal on up to eight separate current inputs.

Twelve time-slots are available, enabling twelve separate measurements per sampling period.

The data output and functional configuration utilise an I2C interface on the ADPD4001 or a serial port interface (SPI) on the ADPD4000. The control circuitry includes flexible LED signalling 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 ADPD4000/ADPD4001 to be a sensor hub for synchronous measurements of photodiodes, biopotential electrodes, resistance, capacitance, and temperature sensors.
