Product Introduction

Overview

The ADS1299-6PAG is a low-noise, 6-channel, 24-bit analog-to-digital converter (ADC) designed by Texas Instruments for biopotential measurements. This device is part of the ADS1299 family, which includes 4-, 6-, and 8-channel variants. It is particularly suited for medical instrumentation applications such as electroencephalogram (EEG), electrocardiography (ECG), fetal ECG, sleep study monitors, and bispectral index (BIS) monitoring. The ADS1299-6PAG integrates high-resolution simultaneous-sampling delta-sigma (ΔΣ) ADCs, programmable gain amplifiers (PGAs), and various built-in features to enhance performance and reduce system size, power, and cost.
