HX3605 is an ultra-low power, high performance optical sensor with I2C interface for Wearable, Heart-Rate Monitor and Bio-sensor. HX3605 integrates a transmitter and a receiver. The receiver has an on-chip photodiode, an offset IDAC and a high-resolution ADC. The transmitter has three LED driver ports sharing a 6bit current driver. Both transmitting and receiving path have very high dynamic range, which is desirable to process small PPG signals.
