And confirm the auxilliary supplies of +54 and +55 and - 54 and -55 volts DC from the regulator transistors Q801 and 802. Webamplifiers achieve high dc precision through a continuously running calibration mechanism that is implemented on-chip. With a typical input offset of 1 µV, a temperature-related drift of 20 nV/ºC, and a long-term drift of 20 nV/month, these amplifiers satisfy even the highest requirements of dc accuracy.
