The MAX86165/MAX86168 is an ultra-low-power, completely integrated, optical data acquisition system. On the transmitter side, the MAX86165 has a programmable low-noise LED driver with an IR emitter while the MAX86168 adds a Green emitter. On the receiver side, the MAX86165/MAX86168 comprises a high efficiency PIN photodiode and an optical readout channel. The optical readout has a low-noise signal conditioning analog front end (AFE), including 20-bit analog‐to‐digital converter (ADC) and an industry-leading ambient light cancellation (ALC) circuit. Due to the low power consumption, compact size, ease and flexibility of use, the MAX86165/MAX86168 is ideal for a wide variety of optical sensing applications such as heart rate detection and proximity sensing in small spaces such as ear buds.
The MAX86165/MAX86168 operates on a single 2.7V to 5.5V VLED supply voltage. Each device has a 128-word built-in FIFO. The MAX86165/MAX86168 is available in a 10-pin OLGA package with compact package dimensions of 2mm x 2.5mm x 0.82mm and operates over -40ºC to +85ºC temperature range.
