ADS1191
Description
The ADS1191/2 are a family of multichannel, simultaneous sampling, 16-bit, delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator. The ADS1191/2 incorporate all of the features that are monly required in portable, low-power medical electrocardiogram (ECG), sports, and fitness applications.
