Pin Description
Typical Application Circuit
A typical application circuit for the ACHS-7124/7125 product series consists of a bypass capacitor and a filter capacitor as
additional external components. On the input side, pins 1 and 2 are shorted together, and pins 3 and 4 shorted together. The
output voltage is directly measured from the V
OUT
pin.
