AFEs for medical applications

28 April 2010 Analogue, Mixed Signal, LSI

New from Texas Instruments are 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. The eight-channel, 24-bit ADS1298 reduces component count and power consumption as compared to discrete implementations, with a power efficiency of 1 mW/channel, while allowing customers to achieve high levels of diagnostic accuracy. The chip integrates eight low-noise PGAs; eight high-resolution, simultaneous sampling ADCs; an amplifier for right-leg drive; amplifiers for Wilson Centre Terminal (WCT) and Goldberger Terminals (GCT); digital pace detection capability; continuous lead-off detection; onboard oscillator and reference.
