Product Overview

ADPD4100 is a multimodal sensor front end. It operates as a complete multimodal sensor front end, stimulating up to eight light emitting diodes (LEDs) and measuring the return signal on up to eight separate current inputs. Twelve time slots are available, enabling 12 separate measurements per sampling period. The control circuitry includes flexible LED signalling and synchronous detection. The devices use a 1.8V analogue core and 1.8V/3.3V compatible digital input/output (I/O). 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 It is 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.
  • Multimodal analogue front end, on-chip digital filtering
  • Dual-channel processing with simultaneous sampling
  • 12 programmable time slots for synchronized sensor measurements
  • Flexible input multiplexing to support differential and single-ended sensor measurements
  • 8 LED drivers, 4 of which can be driven simultaneously
  • Flexible sampling rate from 0.004Hz to 9KHz using internal oscillators
  • SNR of transmit and receive signal chain is 100dB
  • AC ambient light rejection is 60dB typ upto 1KHz, 400mA total LED peak drive current
  • Operating temperature is -40°C to +85°C
  • Package style is 35-ball wafer level chip scale [WLCSP]
