Overview: Click here for production status of specific part numbers. MAX86140/ MAX86141 Best-in-Class Optical Pulse Oximeter and Heart-Rate Sensor for Wearable Health.

General Description

The MAX86140/MAX86141 are ultra-low-power, completely integrated, optical data acquisition systems.

On the transmitter side, the MAX86140/MAX86141 have three programmable high-current LED drivers that can be configured to drive up to six LEDs using an external 3x2:1 mux.

With two MAX86140/MAX86141 devices working in master-slave mode, the LED drivers can drive up to twelve LEDs using an external 3x2:1 mux.

Key Features

  • Complete Single and Dual-Channel Optical Data Acquisition System.
  • Optimized Architecture for Transmissive and Reflective Heart Rate or SpO2 Monitoring.
  • Low Dark Current Noise of < 50pA RMS (Sample to Sample 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.
  • Excellent Dynamic Range > 89dB in White Card Loop-Back Tes.
