The MAX86177 is an ultra-low-power optical data acquisition system with both transmit and receive channels. On the transmitter side, it has two, high-current 8-bit programmable LED drivers and supports up to six LEDs. On the receiver side, it has four low-noise charge integrating front-ends that each includes independent 20-bit analog-to-digital converters (ADCs) and best-in-class ambient light cancellation (ALC) circuits, producing the highest performing integrated optical data acquisition system in the market today.
Due to its low power consumption, compact size, ease and flexibility of use, the MAX86177 is ideal for a wide variety of optical sensing applications such as pulse oximetry and heart rate detection.
The MAX86177 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 512-word built-in FIFO. The MAX86177 is available in a 7 x 4 28-bump wafer level package (WLP) with dimensions of 2.83mm x 1.89mm, and operates over -40ºC to +85ºC temperature range.
