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.
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.
