Overview

Description
The AFE4400 is a fully integrated analog front-end (AFE) designed for pulse oximeter applications. It features a low-noise receiver channel with an integrated analog-to-digital converter (ADC), an LED transmit section, and diagnostics for sensor and LED fault detection. The AFE4400 offers flexible timing control and an integrated oscillator for low-jitter clocking. It communicates with external devices via an SPI interface. The device is packaged in a compact QFN-40 package and operates over a temperature range of 0°C to 70°C.

Features
Pulse Oximeter Applications:
Integrated LED driver (H-bridge or push/pull)
95-dB dynamic range
Programmable LED current (up to 50 mA)
Low power consumption (100 μA average LED current)
Receiver Channel:
13 noise-free bits (0.1 Hz to 5 Hz)
Low power consumption (670 μA at 3.3-V supply)
Flexible receive sample time
Programmable transimpedance amplifier
Integrated Diagnostics:
Photodiode and LED open and short detection
Cable on/off detection
Supplies:
Rx: 2.0 V to 3.6 V
Tx: 3.0 V to 3.6 V

Applications
Low-cost medical pulse oximeter applications
Optical heart rate monitors
Industrial photometry applications
