Product Introduction

Overview

The ADS1298CZXGR, produced by Texas Instruments, is a member of the ADS129x family of multichannel, simultaneous sampling, 24-bit, delta-sigma (ΔΣ) analog-to-digital converters (ADCs). These devices are designed with built-in programmable gain amplifiers (PGAs), internal reference, and an onboard oscillator, making them highly suitable for medical electrocardiogram (ECG) and electroencephalogram (EEG) applications. The ADS1298CZXGR enables the development of scalable medical instrumentation systems with reduced size, power, and overall cost.
