Si1175K1-GM Biometric Optical Sensor

LED Configuration

The Si1175K1-GM Biometric Optical Sensor combines the lowest power optical HR solution in the industry with best in class power. The small, integrated module contains lensing, photodiode, AFE/ADC and 1 Green, 1 Red, 1 IR LED Module (all of which can be driven simultaneously), and simplifies optical design. The sensor is capable of capturing high quality PPG waveforms to support continuous HR measurement while consuming less than 50uA of current (LED + Sensors). Other features include a >100dB dynamic range, built-in buffer, I2C/SPI support and support for accelerometer synchronization.

The devices also support Silicon Labs' proprietary, motion compensated HR algorithm, optimized to run on our Gecko MCUs and wireless SoC's. This level of unparalleled integration allows for system level power and performance optimization, and reduces time to market for wearable makers looking to add HR to their system.
