SBAS502A –DECEMBER 2011–REVISED MARCH 2012

Low-Power, 2-Channel, 24-Bit Analog Front-End for Biopotential Measurements

Check for Samples: ADS1291, ADS1292 , ADS1292R

The

ADS1291,

ADS1292,

and

ADS1292R

FEATURES

incorporate all features commonly required in

portable, low-power medical electrocardiogram

(ECG), sports, and fitness applications.

•

Two Low-Noise PGAs and

Two High-Resolution ADCs

(ADS1292 and ADS1292R)

With high levels of integration and exceptional

performance, the ADS1291, ADS1292, and

ADS1292R enable the creation of scalable medical

instrumentation systems at significantly reduced size,

power, and overall cost.

•

Low Power: 335 μW/channel

Input-Referred Noise: 8 μV_PP

(150-Hz BW, G = 6)

•

Input Bias Current: 200 pA

Data Rate: 125 SPS to 8 kSPS

CMRR: –105 dB

The ADS1291, ADS1292, and ADS1292R have a

flexible input multiplexer 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 ADS1291, ADS1292, and

ADS1292R operate at data rates up to 8 kSPS. Lead-

off detection can be implemented internal to the

device, using the device internal excitation current

sink/source. The ADS1292R version includes a fully

integrated respiration impedance measurement

function.

Programmable Gain: 1, 2, 3, 4, 6, 8, or 12

Supplies: Unipolar or Bipolar

–

Analog: 2.7 V to 5.25 V

Digital: 1.7 V to 3.6 V

•

Built-In Oscillator and Reference

The devices are packaged in a 5-mm × 5-mm, 32-pin

thin quad flat pack (TQFP). Operating temperature is

specified from –40°C to +85°C.

DESCRIPTION

RESP

The ADS1291, ADS1292, and ADS1292R are

multichannel, simultaneous sampling, 24-bit, delta-

sigma (ΔΣ) analog-to-digital converters (ADCs) with a

built-in programmable gain amplifier (PGA), internal

reference, and an onboard oscillator.
