Product Overview

The AFE4403 is a fully-integrated analog front-end (AFE) ideally suited for pulse oximeter applications. The device consists of 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 device is a very configurable timing controller. This flexibility enables the user to have complete control of the device timing characteristics. To ease clocking requirements and provide a low-jitter clock to the AFE4403, an oscillator is also integrated that functions from an external crystal. The device communicates to an external microcontroller or host processor using an SPI interface.
  • Fully-Integrated AFE for Pulse Oximeter and Heart Rate Monitoring Applications
  • Integrated Dual LED Driver
  • Option for a Third LED Support for Optimized SPO2, HRM, or Multi-Wavelength HRM
