Functional Description
Power Supply Range HA12232FP is designed to operate on single supply only. Table 1
Product HA12232FP
Supply Voltage Range
Single Supply 6.5 V to 15.0 V
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.
