MAXM86161 - Single-Supply Integrated Optical Module

General Description

The MAXM86161 is an ultra-low-power, completely integrated, optical data-acquisition system.

On the transmitter side, the MAXM86161 has three programmable high-current LED drivers.

On the receiver side, MAXM86161 consists of a high efficiency PIN photo-diode and an optical readout channel.

Key Features

  • Complete Single-Channel Optical Data Acquisition System.
  • Built-In Algorithm Further Enhances Rejection of Fast Ambient Transients.
  • Optimized Architecture for Reflective Heart Rate and SpO2 Monitoring.
  • Low Dark Current Noise of < 50pA RMS (Sample-toSample Variance).
  • Lower Effective Dark Current Noise Achievable through Multiple Sample Modes and On-Chip Averaging.
  • High-Resolution 19-bit Charge Integrating ADC.
  • Three Low-Noise 8-Bit LED Current DACs.
  • Excelle.
