SBAS601D – DECEMBER 2012 – REVISED MAY 2013
OVERVIEW
The AFE4400 is a complete analog front-end (AFE) solution targeted for pulse oximeter applications. The device
consists of a low-noise receiver channel, an LED transmit section, and diagnostics for sensor and LED fault
detection. To ease clocking requirements and provide the low-jitter clock to the AFE, 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. Figure 32 shows a detailed block diagram for the AFE4400. The blocks are
described in more detail in the following sections.
