Auto-zero instrumentation amplifier (INA102)
Auto-zero instrumentation amplifier (INA102)
Auto-zero instrumentation amplifier (INA102) circuit as shown: As shown for the auto-zero instrumentation amplifier. DG5043CJ and DG5040CJ as analog switches, with 200μs control signal controls the analog switch is closed or open. When 200μs control signal is high open days 1 when closed, low level 0 when the switch is turned off, thereby amplifying the signal control circuit is in a state or in auto-zero state of their work, see the following table.
