00 — Overview

What the MC33078 does

The MC33078/9 series are low noise dual and quad operational amplifiers available in MC33078, MC33079, NCV33078, and NCV33079 variants. These bipolar devices feature a 16 MHz gain bandwidth product, 7.0 V/µs slew rate, and 4.5 nV/√Hz input voltage noise. They offer a large output voltage swing of +14.1 V to −14.6 V and low input offset voltage of 0.15 mV. Designed for high-quality audio and data signal processing, they support dual supply operation from ±5.0 V to ±18 V and include the NCV prefix for automotive applications requiring unique site and control change requirements.
