Applications

1. Professional Audio Equipment

Key Features Utilized: Its ultra-low noise (as low as 4.5 nV/√Hz), low total harmonic distortion (THD), and wide output swing make it ideal for

high-end audio gear.

Typical Applications: Mixing consoles, audio preamplifiers, equalizers, effects processors, and high-fidelity (Hi-Fi) systems.

2. Precision Measurement and Test Equipment

Key Features Utilized: Low input bias current, high open-loop gain, and good stability enable accurate amplification of weak signals.

Typical Applications: Sensor amplifiers (e.g., for strain gauges, thermocouples), data acquisition systems, medical instruments, and laboratory equipment.

3. Active Filters and Signal Conditioning

Key Features Utilized: High slew rate (7 V/µs) and sufficient gain bandwidth product (GBW: 16 MHz) allow it to handle high-frequency signals without distortion.

Typical Applications: Anti-aliasing filters, audio crossovers, and signal conditioning circuits in communication systems.

4. Industrial Control Systems

Key Features Utilized: Wide operating supply range (±1.5V to ±18V) and good stability make it adaptable to demanding industrial environments.

Typical Applications: Process control, motor drive control loops, analog computation, and voltage reference buffering.

Description

The MC33078/9 series is a family of high quality monolithic amplifiers employing Bipolar technology with innovative high performance concepts for quality audio and data signal processing applications. This family incorporates the use of high frequency PNP input transistors to produce amplifiers exhibiting low input voltage noise with high gain bandwidth product and slew rate. The all NPN output stage exhibits no deadband crossover distortion, large output voltage swing, excellent phase and gain margins, low open loop high frequency output impedance and symmetrical source and sink AC frequency performance.

The MC33078/9 family offers both dual and quad amplifier versions and is available in the plastic DIP and SOIC packages (P and D suffixes).
