说明

The MAX86170B is an ultra-low-power optical data acquisition system with both transmit and receive channels. On the transmitter side, the MAX86170B has four LED driver output pins, programmable from three high-current, 8-bit LED drivers. On the receiver side, MAX86170B has a low-noise charge integrating front-end that includes a 20-bit ADC and best-in-class ambient light cancellation (ALC) circuit, 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 MAX86170B is ideal for a wide variety of optical sensing applications such as pulse oximetry and heart rate detection.

The MAX86170B 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 MAX86170B is available in a compact WLP package 2.78 x 1.71mm with 6 x 4, 0.4mm ball pitch.
