AFE4400SPO2EVM Datasheet PDF - TI

The AFE4400SPO2EVM is intended for evaluating AFE4400. The AFE4400 is a fully integrated AFE ideally suited for Pulse Oximeter applications and consist of low noise receive channel, the LED transmit section and diagnostics for sensor and LED fault detection. The AFE4400 is a very highly configurable timing controller enabling the user to have complete control of the device timing characteristics. The device also has an integrated oscillator working off an external crystal to ease clocking requirements and provide a low jitter clock to the AFE4400. The device communicates to an external host processor using the serial peripheral interface (SPI).
