Unused Circuits It is recommended to apply the connection (see Figure 63) and set the non-inverting input pin at a potential within the Input Common-mode Voltage Range (VICM) for any unused circuit. 2. Input Voltage Regardless of the supply voltage, applying VEE+36V to the input pin is possible without causing deterioration of the electrical characteristics or destruction. 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. 3. Power Supply (Single/Dual) The operational amplifiers operate when the voltage supplied is between VCC pin and VEE pin. Therefore, the single supply operational amplifiers can be used as dual supply operational amplifiers as well. 4. IC Handling When pressure is applied to the IC through warp on the printed circuit board, the characteristics may fluctuate due to the piezo effect. Be careful with the warp on the printed circuit board. 5. The IC Destruction Caused by Capacitive Load The IC may be damaged when VCC pin and VEE pin is shorted with the charged output pin capacitor. When IC is used as an operational amplifier or as an application circuit where oscillation is not activated by an output capacitor, output capacitor must be kept below 0.1µF in order to prevent the damage mentioned above.
