Product Overview

ADPD4101 is a multimodal sensor front end. It stimulates upto eight light emitting diodes (LEDs) and measuring the return signal on upto eight separate current inputs. The analogue front end (AFE) rejects signal offsets and corruption from asynchronous modulated interference, typically from ambient light, eliminating the need for optical filters or externally controlled dc cancellation circuitry. Multiple operating modes are provided, enabling the device to be a sensor hub for synchronous measurements of photodiodes, bio potential electrodes, resistance, capacitance, and temperature sensors. It is widely used in application such as wearable health and fitness monitors: heart rate monitors, (HRMs), heart rate variability (HRV), stress, blood pressure estimation, SpO2, hydration, body composition, industrial monitoring: CO, CO2, smoke, and aerosol detection, home patient monitoring etc.
  • Flexible input multiplexing to support differential and single-ended sensor measurements
  • Flexible sampling rate from 0.004Hz to 9kHz using internal oscillators
  • On-chip digital filtering, SPI and I²C communications supported
  • SNR of transmit and receive signal chain is 100dB
  • AC ambient light rejection is 60dB upto 1kHz
  • Total LED peak drive current is 400mA
  • Total system power dissipation is 30µW (combined LED and AFE power)
  • Continuous PPG measurement at 75dB SNR, 25Hz ODR, 100nA/mA CTR
  • Operating temperature range is −40°C to +85°C
  • Packaging style is 33-ball wafer level chip scale package [WLCSP]
