# MAXM86161AEFD+ (Component) ## Description Optical Sensor I2C Output Optical heart rate and SpO₂ sensor module that integrates a PIN photodiode, three programmable LED drivers, a low-noise analog front end with a 19-bit ADC, ambient light cancellation, and a 128-word FIFO for optical data acquisition. It operates from a 3.0 V to 5.5 V LED supply, supports an I²C-compatible interface, and is designed for reflective heart rate and pulse oximetry measurements in low-power wearable applications. #OpticalSensor #HeartRateSensor #SpO2Sensor #OpticalModule #BiometricSensor #I2C #AnalogDevices ## Component Details - **Owner:** silicon-yard - **Created:** 7/22/2026 - **Last Updated:** 7/22/2026 - **Visibility:** Public - **Manufacturer Name:** Analog Devices - **Manufacturer Part Number:** MAXM86161AEFD+ - **Datasheet URL:** https://www.analog.com/media/en/technical-documentation/data-sheets/maxm86161.pdf - **Package or Case Code:** 14-pin OLGA - **Part Type:** Sensor - **License:** https://creativecommons.org/licenses/by/4.0/ - **Symbol Style:** parametric-v1 - **Used in:** 1 project ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
