24-Bit Dual-Channel Analog Front-End for ECG and Respiration — integrating high-resolution delta-sigma ADCs, programmable gain amplifiers, and SPI interface for portable and wearable medical applications.
Product Overview
The ADS1292RIRSMR from Texas Instruments is a highly integrated, dual-channel analog front-end designed for ECG and respiration measurement.
It incorporates two 24-bit delta-sigma ADCs, low-noise programmable gain amplifiers (PGAs), a right-leg drive (RLD) amplifier, lead-off detection circuitry, and a respiration impedance measurement block.
With high resolution and ultra-low power consumption, it is ideal for portable medical monitors, wearable health devices, and remote patient monitoring systems.
The device communicates via SPI interface and operates from a single 2.7V–5.25V supply. Packaged in VQFN-28 (RSM), it provides excellent size-to-performance balance.
