Abstract: WITH THE ADVENT of low cost 12b data conversion systems, the need t o extend the true instrumentation amplifier (in-amp) function t o this realm is evident. This paper will describe a self-contained systems level in-amp designed t o address this need. Errors that cannot be eliminated by automatic zeroing and scale factor adjust, such as nonlinearity, noise and settling time, are reduced to low levels.Previous monolithic in-amps reported in the literature' J , 3 have relied upon some form of wide range control…
