EVALUATION KIT AVAILABLE Click here for production status of specific part numbers. MAXM86161 Single-Supply Integrated Optical Module
for HR and SpO2 Measurement General Description The MAXM86161 is an ultra-low-power, completely integrated, optical data-acquisition system. On the transmitter
side, the MAXM86161 has three programmable highcurrent LED drivers. On the receiver side, MAXM86161
consists of a high efficiency PIN photo-diode and an optical readout channel. The optical readout has a low-noise
signal conditioning analog front-end (AFE), including
19-bit ADC, an industry-lead ambient light cancellation
(ALC) circuit, and a picket fence detect and replace
algorithm. Due to the low power consumption, compact
size, easy, flexible-to-use, and industry lead ambient light
rejection capability of the MAXM86161, the device is ideal
for a wide variety of optical sensing applications such as
heart rate detection and pulse oximetry.
The MAXM86161 operates on a 3.0V to 5.5V VLED
single supply voltage. It supports a standard compatible
interface and fully autonomous operation. Each device
has a large 128-word built-in FIFO. The MAXM86161 is
available in compact 2.9mm x 4.3mm x 1.4mm, 14-pin
OLGA package. Applications ●● Optimized for In-Ear Applications
