Single Supply
Power Supply Voltage Range
6.5 V to 15.0 V
Reference Voltage
These devices provide the reference voltage of half the supply voltage that is the signal grounds. As the
peculiarity of these devices, 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.
