Note: In order for the microprocessor to service subroutines and interrupts, the stack pointer must be

dimensioned in the user’s program.

For amplification of DC input signals, a major system error is the input offset voltage of the amplifiers used for

the preamp. Figure 43 is a gain of 100 differential preamp whose offset voltage errors will be cancelled by a

zeroing subroutine which is performed by the INS8080A microprocessor system. The total allowable input offset

voltage error for this preamp is only 50 µV for /

⁄4 LSB error. This would obviously require very precise amplifiers.

The expression for the differential output voltage of the preamp is:
