Functional Description
Power Supply Range
HA12232FP is designed to operate on single supply only.

6.5 V to 15.0 V
Single Supply
Reference Voltage
HA12232FP provides the reference voltage of half the supply voltage that is the signal grounds. As the peculiarity of
this device, the capacitor for the ripple filter is very small about 1/100 compared with their usual value. The block
diagram is shown as figure 1.
