3 Description
The ADS1294, ADS1296, ADS1298 (ADS129x) and
ADS1294R, ADS1296R ADS1298R (ADS129xR) 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 ADS129x and ADS129xR incorporate all of the features that are commonly required in medical
electrocardiogram (ECG) and electroencephalogram
(EEG) applications. With high levels of integration
and exceptional performance, the ADS129x and
ADS129xR enables the development of scalable
medical instrumentation systems at significantly reduced size, power, and overall cost.
The ADS129x and ADS129xR have a flexible input
multiplexer (mux) per channel that can be
independently connected to the internally-generated
signals for test, temperature, and lead-off detection.
Additionally, any configuration of input channels can
be selected for derivation of the right leg drive (RLD) output signal. The ADS129x and ADS129xR operate
at data rates as high as 32 kSPS, thereby allowing
the implementation of software pace detection. Lead•
off detection can be implemented internal to the
device, either with a pullup or pulldown resistor, or an excitation current sink or source. Three integrated
amplifiers generate the Wilson central terminal (WCT)
and the Goldberger central terminals (GCT) required
for a standard 12-lead ECG. The ADS129xR versions
include a fully integrated, respiration impedance
measurement function. Multiple ADS129x and
ADS129xR devices can be cascaded in high channel
count systems in a daisy-chain configuration.
Package options include a tiny 8-mm × 8-mm,
64-ball BGA, and a TQFP-64. The ADS129x BGA
version is specified over the commercial temperature
range of 0°C to 70°C. The ADS129xR BGA and
ADS129x TQFP versions are specified over the
industrial temperature range of –40°C to +85°C.
