GENERAL DESCRIPTION
The AD8231-EP is a low drift, rail-to-rail, instrumentation
amplifier 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-EP 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 for
gains of 1 to 32. 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 80 dB for G = 1, increasing to 110 dB at
higher gains.
The AD8231-EP 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-EP includes a shutdown feature that reduces current
to a maximum of 1 μA. In shutdown, both amplifiers also have
a high output impedance, which allows easy multiplexing of
multiple amplifiers without additional switches.
The AD8231-EP is specified over the military temperature
range of 55°C to +125°C. It is available in a 4 mm × 4 mm 16-
lead LFCSP.
Additional application and technical information can be found
in the AD8231 data sheet.
