Maxim Integrated MAX86141ENP+T Biometric Sensor, 20-Pin, THIN-WLP-20 / 2236441

The Maxim Integrated MAX86140 are ultra-low-power, completely integrated, optical data acquisition systems. On the transmitter side, the MAX86140 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 devices working in master-slave mode, the LED drivers can drive up to twelve LEDs using an external 3x2:1 mux. On the receiver side, MAX86141 has two optical readout channels that can operate simultaneously. it can operate simultaneously. The devices have low noise signal conditioning analog front-end (AFE) including 19-bit ADC, an industry-lead ambient light cancellation (ALC) circuit, and a picket fence detect and replace function.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
