DESCRIPTION
The
ADS1294/6/8/4R/6R/8R
are
a
family
of
multichannel,
simultaneous
sampling,
24-bit,
delta-sigma (
ΔΣ) analog-to-digital converters (ADCs)
with built-in programmable gain amplifiers (PGAs),
internal reference, and an onboard oscillator. The
ADS1294/6/8/4R/6R/8R incorporate all of the features
that
are
commonly
required
in
medical
electrocardiogram (ECG) and electroencephalogram
(EEG) applications.
