10 Hertz Current Source
Rotary switch SW5 10 Hz Amp Adj injects a 10 Hz square wave signal into the
current-sense measurement circuit. This function is provided to demonstrate the
PAC1710 and PAC1720 devices’ ability to attenuate circuit noise. The steady-state
current consumption for the rotary switch SW1 Steady-State settings, in conjunction
with the J16 jumper position which sets the range, are shown in
. The square
wave amplitude is adjustable by rotary switch SW5 to obtain the pulse consumption
shown in
.
