MAX86141ENP+T

MAX86141 is a ultra-low-power, completely integrated, optical data acquisition systems. On the transmitter side, this device has three programmable high-current LED drivers that can be configured to drive up to six LEDs using an external 3x2:1 mux. With device working in host-server mode, the LED drivers can drive upto twelve LEDs using an external 3x2:1 mux. On the receiver side, the device has two optical readout channels that can operate simultaneously. This device has low noise signal conditioning analogue front-end (AFE) including 19-bit ADC, an industry-lead ambient light cancellation (ALC) circuit, and a picket fence detect and replace function. It is used in applications such as wearable devices for fitness, wellness and medical applications, optimized for wrist, finger, ear, and other locations, optimized performance to detect, optical heart rate, oxygen saturation (SpO2), muscle oxygen saturation (SmO2 and StO2).

• Complete single and dual-channel optical data acquisition system
• Optimized architecture for transmissive and reflective heart rate or SpO2 monitoring
• Lower effective dark current noise achievable through multiple sample modes and on-chip averaging
• High-resolution, 19bit charge integrating ADC, three low-noise, 8bit LED current DACs
• Excellent dynamic range <gt/> 89dB in white card loop-back test (sample-to-sample variance)
• <gt/> 100μA ambient photodetector current, 70dB ambient rejection at 120Hz
• Operating temperature is -40°C to +85°C
• Package style is 20-pin WLP
