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, MAX86140 consists of a single optical readout channel. 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.
