Precautions  
1) Unused circuits  
When there are unused circuits, it is recommended that they be connected as in Figure 103,  
Vcc  
setting the non-inverting input terminal to a potential within the in-phase input voltage range (VICR).  
2) Input terminal voltage  
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.  
connect  
to Vicm  
Please note that the circuit operates normally only when the input voltage is within the common mode  
input voltage range of the electric characteristics.  
GND  
3) Power supply (single / dual)  
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.  
Fig.103 Disable circuit example  
4) Power dissipation (Pd)  
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.  
5) Short-circuits between pins and erroneous mounting  
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.  
6) Operation in a strong electromagnetic field  
Operation in a strong electromagnetic field may cause malfunctions.  
7) Radiation  
This IC is not designed to withstand radiation.  
8) IC handing  
Applying mechanical stress to the IC by deflecting or bending the board may cause fluctuation of the electrical characteristics due to piezoelectric (piezo)  
effects.  
9) IC operation  
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.  
10) Board inspection  
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.  
11) Output capacitor  
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.
