AFE4490 Integrated Analog Front End

Texas Instruments AFE4490 Integrated Analog Front End is a fully-integrated AFE that is ideally suited for pulse-oximeter applications. This TI device consists of a low-noise receiver channel with a 22-bit analog-to-digital converter (ADC), an LED transmit section, and diagnostics for sensor and LED fault detection. AFE4490 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 AFE4490, 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.
