MAXM86161A Single-Supply Integrated Optical Module

Analog Devices MAXM86161A Single-Supply Integrated Optical Modules are ultra‑low‑power, fully integrated optical data‑acquisition modules. The ADI MAXM86161A features three programmable high‑current LED drivers on the transmitter side and a high‑efficiency PIN photodiode paired with an optical readout channel on the receiver side. The optical readout includes a low‑noise analog front end (AFE) with a 19‑bit analog-to-digital converter (ADC), an industry‑leading ambient light cancellation (ALC) circuit, and a picket‑fence detection and replacement algorithm. Thanks to the low power requirements, compact form factor, ease of use, and excellent ambient‑light rejection, the MAXM86161A modules are well-suited for a broad range of optical sensing applications, including heart‑rate monitoring and pulse oximetry.
