MAX86140ENP+

The MAX86140 is an ultra-low-power, completely integrated, optical data acquisition system. On the transmitter side, the MAX86140 has three programmable high-current LED drivers that can be configured to drive up to six LEDs.

• Complete single channel, optical data acquisition system
• Built-in algorithm further enhances rejection of fast ambient transients
• Optimized architecture for transmissive and reflective heart rate or SpO2 monitoring
• Low dark current noise of less than 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
