Frequently asked questions
Can the MC33078 run from a single 5 V supply?
Yes. The device is specified for single-supply operation over a wide range, so 5 V is within its supply range. Check the output swing requirements of your circuit against the datasheet.
How does it differ from the NE5534?
Both are audio-grade operational amplifiers. The MC33078 contains two amplifiers in one package, while the NE5534 is a single amplifier that is designed for dual-supply operation.
