When there are unused circuits, it is recommended that they be connected as in Figure 7,
setting the non-inverting input terminal to a potential within the in-phase input voltage range (VICR).
Applying GND + 32V to the input terminal is possible without causing 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 is applied between Vcc and GND.
Therefore, the single supply op-amp 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 of chip temperature, including
reduced current capability. Therefore, please take into consideration the power dissipation (Pd) under the 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 GND may also result in IC destruction.
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 and
GND, crossover distortion occurs at the changeover between discharging and charging of the output current. Connecting a resistor between the output
terminal and GND and increasing the bias current for Class A operation will suppress crossover distortion.
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.
Discharge of the external output capacitor to Vcc is possible via internal parasitic elements when Vcc is shorted to GND, causing damage to the internal
circuitry due to thermal stress. Therefore, when using this IC in circuits where oscillation due to output capacitive load does not occur, such as in voltage
comparators, use an output capacitor with a capacitance less than 0.1μF.
