Analog front-end chip for EEG and ECG medical equipments from TI

Texas Instruments has released integrated analog front end (AFEs) IC for portable medical electronic equipments such as electrocardiogram (ECG) and electroencephalogram (EEG) devices. This new chip ADS1298 is an eight-channel, 24-bit analog chip with a power efficiency of 1 mW/channel.

"Until now, high power consumption and bulky designs limited the portability of ECG and EEG equipment," said Art George, senior vice president of TI's High-Performance Analog business unit. "With the ADS1298's low power consumption and high integration, manufacturers can develop equipment that is portable, compact and affordable. This will make it easier for doctors to monitor vital parameters over the long term for more accurate clinical data, while increasing patient comfort with devices that can easily be carried, concealed or worn."

The key features of ADS1298 are,

Eight low-noise programmable gain amplifiers (PGAs).
Eight 24 bit simultaneous sampling analog-to-digital converters (ADCs)
Has integrated amplifier for right-leg drive.
Has integrated amplifiers for Wilson Central Terminal (WCT) and Goldberger Terminals (GCT).
Offer digital pace detection capability.
Features continuous lead-off detection.
Has onboard oscillator and reference for smaller footprint and low-power applications.
input-referred noise of 4-uVpp (typical).
