The Texas Instruments AFE4403 is a highly integrated analog front-end (AFE) suitable for applications such as clinical fingertip pulse oximetry and optical heart-rate monitoring (HRM). This device offers a 22-bit resolution for precise signal capture and an SPI interface for communication.
Key electrical specifications include a programmable gain range from 10 kΩ to 4 MΩ and an input clock frequency range of 4 MHz to 60 MHz. The AFE4403 supports dual LED drivers and can accommodate a third LED. It operates within a supply voltage range of 2.0 V to 3.6 V for Rx and 3.0 V to 5.25 V for Tx.
The device is housed in a compact DSBGA-36 package measuring 3.07 mm x 3.07 mm x 0.5 mm. It is specified for an operating temperature range of -20°C to 70°C, making it suitable for various environmental conditions.
Features like integrated ambient light estimation and subtraction, along with fault diagnostics for photodiode and LED open/short detection, enhance its usability in demanding applications.
