The MAX86171 is an ultra-low-power optical data acquisition system with both transmit and receive channels. On the transmitter side, the MAX86171 has nine LED driver output pins, programmable from three high-current, 8-bit LED drivers. On the receiver side, MAX86171 has two low-noise charge integrating front-ends that each include independent 19.5 bit ADCs and best-in-class ambient light cancellation (ALC) circuits, producing the highest performing integrated optical data acquisition system on the market today.
Due to its low power consumption, compact size, ease and flexibility of use, the MAX86171 is ideal for a wide variety of optical sensing applications such as pulse oximetry and heart rate detection.
The MAX86171 operates on a 1.8V main supply voltage and a 3.1V to 5.5V LED driver supply voltage. The device supports both I2C and SPI compatible interfaces in a fully autonomous way. The device has a large 256-word built-in FIFO. The MAX86171 is available in a compact 28-bump WLP package.
