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).
