Si1181-GM Biometric Optical Sensor

The Si1181-GM Biometric Optical Sensor combines the lowest power optical HR solution in the industry with best in class power. It combines a photodiode, analog front end and ADC in a small 3 x 3 QFN device, and allows for the ultimate flexibility in optical design while reducing BOM size. The sensor is capable of capturing high quality PPG waveforms to support continuous HR measurement while consuming less than 50uA of cureent (LED + Sensors). Other features include a > 100dB dynamic range, built-in buffer, I2C/SPI support and support for accelerometer synchronization.

Purchasing Information: Available in limited quantities for qualified customers (NDA required).
