The AFE4400RHAT from Texas Instruments is a fully-integrated analog front-end (AFE) specifically designed for applications such as heart-rate monitors and low-cost pulse oximeters. This IC features a high dynamic range of 95 dB and provides 22-bit resolution for precise signal acquisition.
Key electrical characteristics include a programmable LED driver with 8-bit current resolution up to 50 mA, and a receive channel with 13 noise-free bits. The device operates within a supply voltage range of 2.0 V to 3.6 V for the Rx supply and 3.0 V to 5.25 V for the Tx supply. It also includes integrated digital ambient light estimation and subtraction capabilities.
The AFE4400RHAT is housed in a compact 40-VQFN (6 mm x 6 mm) package, suitable for surface mounting. The specified operating temperature range is from 0°C to 70°C. Integrated fault diagnostics for photodiode and LED open/short detection, as well as cable on/off detection, enhance its reliability in various applications.
