This reference design is suitable for micro optical heart rate monitor measurement solutions (without chest straps) specifically for wearable or mobile applications. Small modules make it easy to connect to smartphones, tablets and wearables. With TI's AFE4403 AFE, the optical HRM design process can be accelerated and simplified while still ensuring the measurement performance required for critical fitness designs. This design is smaller than the TIDA-00011.
