The advent of instrumentation amplifiers with digital gain switching offers obvious advantages, such as board-space saving, higher reliability because of fewer solder joints, and lower total cost. These valuable features stem from the fact that the gain-setting networks are integral parts of the monolithic ICs. This feature makes these IC amplifiers much less sensitive to stray electromagnetic fields because the area of internal resistors is a negligible fraction of the previously used discrete gain-setting resistors. Moreover, the value ...
