描述 Description

The Si1185-GM Biometric Optical Sensor combines the lowest power optical heart rate solution in the industry with best-in-class power. It combines a photodiode, analog front-end and ADC in a small 3x3 QFN device, and allows for the ultimate flexibility in optical design while reducing BOM size. The sensor can capture high quality PPG waveforms to support continuous heart rate (HR) measurement while consuming less than 50 uA of current (LED + Sensors). Other features include a > 100 dB dynamic range, built-in buffer, I2C/SPI support and support for accelerometer synchronization.
