We used to build amplifiers for digital scales (weighing Instrumentation) where we would sample a full scale voltage reference and a ground reference and from there digitally cancel out gain and baseline drift. Nowadays the amplifier itself can do a lot of this correction. We used to call these amplifiers “coppers” referring to the process
