NP TI ADI1298

Dallas, Tex.—Texas Instruments Inc. has introduced the first in a family of fully integrated analog front ends (AFEs) for portable and high-end electrocardiogram (ECG) and electroencephalogram (EEG) equipment, as well as patient monitoring and consumer medical applications.

According to TI, the eight-channel, 24-bit ADS1298 reduces component count and power consumption by up to 95 percent as compared to discrete implementations, with a power efficiency of 1 mW/channel, while allowing customers to achieve high levels of diagnostic accuracy.
The ADS1298 integrates all common features required for ECG and EEG front ends, including the following: eight low-noise programmable gain amplifiers (PGAs); eight high-resolution, simultaneous sampling analog-to-digital converters (ADCs); integrated amplifier for right-leg drive; integrated amplifiers for Wilson Center Terminal (WCT) and Goldberger Terminals (GCT); digital pace detection capability; continuous lead-off detection; and an onboard oscillator and reference for smaller footprint and low-power applications.
