GENERAL DESCRIPTION  
The AD8231 also includes an uncommitted op amp that can be  
used for additional gain, differential signal driving or filtering.  
Like the in-amp, the op amp has an auto-zero architecture, rail-  
to-rail input, and rail-to-rail output.  
The AD8231 is a low drift, rail-to-rail, instrumentation ampli-  
fier with software programmable gains of 1, 2, 4, 8, 16, 32, 64, or  
128. The gains are programmed via digital logic or pin  
strapping.  
The AD8231 includes a shutdown feature that reduces current  
to a maximum of 1 μA. In shutdown, both amplifiers also have  
a high output impedance. This allows easy multiplexing of  
multiple amplifiers without additional switches.  
The AD8231 is ideal for applications that require precision  
performance over a wide temperature range, such as industrial  
temperature sensing and data logging. Because the gain setting  
resistors are internal, maximum gain drift is only 10 ppm/°C.  
Because of the auto-zero input stage, maximum input offset is  
15 μV and maximum input offset drift is just 50 nV/°C. CMRR  
is also guaranteed over temperature at 80 dB for G = 1, increas-  
ing to 110 dB at higher gains.  
The AD8231 is specified over the extended industrial tempera-  
ture range of −40°C to +125°C. It is available in a 4 mm × 4 mm  
16-lead LFCSP (chip scale).
