ADPD7000BCBZR7

ADPD7000BCBZR7 is a highly integrated analogue front end (AFE) designed for measuring various vital signals. The optical channel is designed as an optical transceiver, stimulating up to eight light-emitting diodes (LEDs) and measuring the return signal on up to four separate current inputs. The signal chain 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 applications such as wearable health and fitness monitors: heart rate, heart rate variability, the saturation level of pulse oxygen, body impedance analysis, hydration analysis, cuff-less non-invasive blood pressure, clinical patient monitors small bed-side patient, home portable patient, and small remote patient, industrial monitoring: particle, aerosol, and gas detection, conductivity detection.

• Multimodal analogue front end, 4-channel processing with simultaneous sampling
