The Texas Instruments AFE4403YZPR is a highly integrated Analog Front End (AFE) designed for applications such as heart-rate monitors and low-cost pulse oximeters. This device offers a 22-bit resolution for precise data conversion and utilizes an SPI interface for communication.
Key electrical specifications include a wide programmable gain range from 10 kΩ to 4 MΩ and a low power consumption of less than 650 μA. It supports dual LED drivers with programmable current up to 100 mA and features high dynamic range on both transmit (up to 110 dB) and receive channels (up to 105 dB).
The AFE4403YZPR operates with supply voltages ranging from 2V to 3.6V for the Rx channel and 3V to 5.25V for the Tx channel. It is housed in a compact 36-DSBGA package, suitable for surface mounting. The operating temperature range is -20°C to 70°C.
This AFE includes integrated digital ambient estimation and subtraction, flexible clocking options, and fault diagnostics for photodiode and LED open/short detection, making it a versatile solution for optical sensing applications.
