SBAS566A –DECEMBER 2011–REVISED SEPTEMBER 2012  
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  
1
FEATURES  
are commonly required in portable, low-power  
medical electrocardiogram (ECG), sports, and fitness  
applications.  
23  
•
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 μVPP  
(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

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.
