When there are unused circuits, it is recommended that they be connected as
in Fig.7, setting the non-inverting input terminal to a potential within the
in-phase input voltage range (VICM).
Applying Vcc
deterioration of the electrical characteristics or destruction, irrespective of
the supply voltage. However, this does not ensure normal circuit operation.
Please note that the circuit operates normally only when the input voltage is
within the common mode input voltage range of the electric characteristics.
The op-amp operates when the voltage supplied is between Vcc
Therefore, the single supply op-mp can be used as a dual supply op-amp as well.
Using the unit in excess of the rated power dissipation may cause deterioration in electrical characteristics due to the rise in chip temperature, including
reduced current capability. Therefore, please take into consideration the power dissipation (Pd) under actual operating conditions and apply a sufficient
margin in thermal design. Refer to the thermal derating curves for more information.
Incorrect mounting may damage the IC. In addition, the presence of foreign substances between the outputs, the output and the power supply, or the output
and Vcc
Operation in a strong electromagnetic field may cause malfunctions.
This IC is not designed to withstand radiation.
Applying mechanical stress to the IC by deflecting or bending the board may cause fluctuation of the electrical characteristics due to piezoelectric (piezo)
effects.
The output stage of the IC is configured using Class C push-pull circuits. Therefore, when the load resistor is connected to the middle potential of Vcc

Connecting a capacitor to a pin with low impedance may stress the IC. Therefore, discharging the capacitor after every process is recommended. In addition,
when attaching and detaching the jig during the inspection phase, ensure that the power is turned OFF before inspection and removal. Furthermore, please
take measures against ESD in the assembly process as well as during transportation and storage.
