With its high levels of integration and exceptional
Input-Referred Noise: 24
μVPP
performance, the ADS1191/2 family enables the
(150-Hz BW, G = 6)
creation of scalable medical instrumentation systems
at significantly reduced size, power, and overall cost.
Input Bias Current: 1 nA
Data Rate: 125 SPS to 8 kSPS
The ADS1191/2 have a flexible input multiplexer per
channel that can be independently connected to the
CMRR: –95 dB
internally-generated signals for test, temperature, and
Programmable Gain: 1, 2, 3, 4, 6, 8, or 12
