SBAS566 –DECEMBER 2011

Low-Power, 2-Channel, 16-Bit Analog Front-End for Biopotential Measurements

Check for Samples: ADS1191, ADS1192

The ADS1191/2 incorporate all of the features that

FEATURES

are commonly required in portable, low-power

medical electrocardiogram (ECG), sports, and fitness

applications.

•

Two Low-Noise PGAs and

Two High-Resolution ADCs (ADS1192)

•

Low Power: 335 μW/channel

With its high levels of integration and exceptional

performance, the ADS1191/2 family enables the

creation of scalable medical instrumentation systems

at significantly reduced size, power, and overall cost.

Input-Referred Noise: 24 μV_PP

(150-Hz BW, G = 6)

•

Input Bias Current: 1 nA

Data Rate: 125 SPS to 8 kSPS

CMRR: –95 dB

The ADS1191/2 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 ADS1191/2

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.

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 Right Leg Drive Amplifier, Lead-Off

Detection, Test Signals

•

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.

Flexible Power-Down, Standby Mode

SPI™-Compatible Serial Interface

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.
