AFE4490SPO2EVM Datasheet PDF - TI

●The AFE4490SPO2EVM evaluation module is intended for evaluating AFE4490 device. The AFE4490 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 AFE4490 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 AFE4490. The device communicates to an external host processor using the serial peripheral interface (SPI). The purpose of the AFE4490SPO2EVM is to expedite evaluation and system development activities related to AFE4490 device.
