Frequently Asked Questions
What is the supply voltage range for the MC33078D?
The MC33078D operates on a dual supply voltage range typically from ±5 V to ±18 V, making it suitable for a wide range of analog circuit designs in both low-power and high-performance applications.
What are typical applications for the MC33078D operational amplifier?
The MC33078D is commonly used in audio preamplifiers, active band-pass and low-pass filters, instrumentation amplifiers, and data acquisition systems. Its 80 dB minimum CMRR and 0.75 µA typical bias current make it well suited for precision signal conditioning and differential measurement circuits.
How does the MC33078D compare to single op-amp alternatives?
The MC33078D integrates two independent op-amps in a single Small Outline Package, reducing board space and component count compared to using two discrete single op-amps. Each amplifier shares the same voltage-feedback architecture with 2 mV max input offset and frequency compensation, providing matched performance for differential or stereo channel designs.
Is the MC33078D compatible with low-voltage systems?
The MC33078D is designed for dual-supply operation and is best suited for systems with at least ±5 V rails. For single-supply or sub-5 V applications, a rail-to-rail alternative may be more appropriate. Check the datasheet for absolute maximum ratings before integrating into low-voltage designs.
