Functional Description

Power Supply Range

HA12231FP is designed to operate on single supply only.

Table 1	Supply Voltage Range
Product	Single Supply
HA12231FP	7.2 V to 12.0 V

Reference Voltage

HA12231FP 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.
