Datasheet Summary
Powered by GS/AI

The AFE4403YZPR is an ultra-small, fully-integrated analog front-end designed for pulse oximeter and heart rate monitoring applications. It features a low-noise receiver channel with a 22-bit ADC, dual LED drivers, and programmable LED current up to 100 mA. The device supports a dynamic range of up to 110 dB for transmission and 105 dB for reception, making it suitable for a wide range of signal amplitudes. It includes integrated diagnostics for sensor and LED fault detection, enhancing reliability in medical applications. The AFE4403 operates with a supply voltage range of 2.0 V to 3.6 V for the receiver and 3.0 V to 5.25 V for the transmitter. It is configurable via an SPI interface and can be clocked using an external crystal, with a pulse frequency ranging from 62.5 SPS to 2000 SPS. The compact DSBGA-36 package measures 3.07 mm x 3.07 mm x 0.5 mm and is specified for an operating temperature range of -20¬8C to 70¬8C. This product is suitable for engineers looking for a comprehensive AFE solution for low-cost medical devices.
