MC33078 — Datasheet Summary, Specs & Alternatives

01 — Overview

This datasheet covers the MC33078/9 and NCV33078/9 low noise dual and quad operational amplifiers. Designed for audio and data signal processing, these bipolar amplifiers feature high frequency PNP inputs for low noise and an all-NPN output stage eliminating crossover distortion. Key parameters include a supply range of ±5.0V to ±18V, voltage noise of 4.5 nV/√Hz, input offset voltage of 0.15 mV, gain bandwidth product of 16 MHz, slew rate of 7.0 V/μs, and total harmonic distortion of 0.002%. The devices offer large output swings up to ±14.6V and are available in PDIP and SOIC packages with RoHS compliance.
