The devices shown here are all zero-drift instrumentation amplifiers, but the Comp A part is not programmable and operates at a much lower bandwidth, leaving Comp B’s part as the main competitor. The ISL2853x and ISL2863x In Amp family has less than half the maximum offset voltage and gain error of the Comp B, and meets or beats almost all of the other key specifications as well. The Renesas devices also have numerous additional gain options, the choice of a differential output, and additional features such as access to the gain stage output for added versatility.
