Mouser now stocks the ADPD4200 multimodal sensor front end from Analog Devices.

The device functions as a complete photometric sensor front end, stimulating up to four LEDs while measuring the return signal on up to four separate current inputs. The device has 12 time slots, allowing 12 separate measurements per sampling period. This sensor incorporates a control circuitry with flexible LED signalling and synchronous detection. The Sensor Front End employs a 1.8V analog core and 1.8V or 3.3V compatible digital input/output. The device provides dual-channel processing with simultaneous sampling, on-chip digital filtering, 400mA total LED peak drive current, and 512-byte FIFO size.

This sensor front end is excellent for multiple applications, including wearable health and fitness monitors, industrial monitoring, and home patient monitoring devices.
