Operational Notes – continued
13. Power Supply(single/dual)
The operational amplifiers operate when the voltage supplied is between VDD and VSS. Therefore, the single supply
operational amplifiers can be used as dual supply operational amplifiers as well.
14. Output Capacitor
If a large capacitor is connected between the output pin and VSS pin, current from the charged capacitor will flow into
the output pin and may destroy the IC when the VDD pin is shorted to ground or pulled down to 0V. Use a capacitor
smaller than 0.1µF between output pin and VSS pin.
15. Oscillation by Output Capacitor
Please pay attention to the oscillation by output capacitor and in designing an application of negative feedback loop
circuit with these ICs.
16. Latch up
Be careful of input voltage that exceed the VDD and VSS. When CMOS device have sometimes occur latch up and
protect the IC from abnormaly noise.
