Kit Overview

The Texas Instruments ADS1298ECGFEADS1298ECGFE/ADS1198ECGFEADS1198ECGFE is a reference design for the ADS1298ADS1298/ADS1198ADS1198 a simultaneous sampling, 24-bit (ADS1298ECGFE)/16-Bit (ADS1198ECGFE), delta-sigma (ΔΣ) analog-to-digital converter (ADC) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator.

The ADS1198ADS1198/ADS1298ADS1298 incorporates all of the features that are commonly required in medical electrocardiogram (ECG) and electroencephalogram (EEG) applications. The ADS1298ECGFEADS1298ECGFE/ADS1198ECGFEADS1198ECGFE can be used with a variety of patient simulators and allows the user to take advantage of the flexible input multiplexer which can be independently connected to the internally-generated signals for test, temperature, and lead-off detection.

The ADS1x98ECG-FE is intended for evaluating the ADS1198ADS1198 and ADS1298ADS1298 for ECG and EEG applications. The digital SPI™ control interface is provided by the MMB0 Modular EVM motherboard that connects to the ADS1x98ECG FE evaluation board. The ADS1x98ECG-FE is NOT a reference design for ECG and EEG applications; rather, its purpose is to expedite evaluation and system development. The output of the ADS1298ADS1298 yields a raw, unfiltered ECG signal.

The MMB0 motherboard allows the ADS1x98 to be connected to the computer via an available USB port.

The ADS1298ADS1298/ADS1198ADS1198 is a family of multichannel, simultaneous sampling, 24-bit (ADS1298)/16-bit (ADS1198), delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with built-in programmable gain amplifiers (PGAs), internal reference, and an onboard oscillator.
