MC33072PG

MC33072PG Description

The MC33072PG from onsemi is a high-performance, general-purpose dual operational amplifier (op-amp) housed in an 8-pin DIP package. Designed for precision analog applications, it operates over a wide supply voltage range of 3V to 44V, making it versatile for both low-voltage and high-voltage systems. With a Gain Bandwidth Product (GBWP) of 4.5 MHz and a slew rate of 13V/µs, it delivers fast signal response and stable amplification, suitable for dynamic signal processing. The device features low input bias current (100 nA) and low input offset voltage (1 mV), ensuring accuracy in sensitive circuits. Its robust 30 mA output current per channel enables driving heavier loads compared to standard op-amps.

MC33072PG Features

• Wide Supply Range: 3V to 44V operation, accommodating diverse power requirements.
• High Slew Rate (13V/µs): Ideal for fast transient response in audio, control systems, and signal conditioning.
• Low Noise & Offset: 1 mV input offset and 100 nA bias current enhance precision in measurement circuits.
• Dual-Channel Design: Two independent op-amps in one package, reducing board space and cost.
• High Output Drive (30 mA/channel): Capable of driving capacitive or low-impedance loads.
• Through-Hole Mounting (DIP-8): Simplifies prototyping and repair in industrial/hobbyist applications.
• Obsolete Status: Still valuable for legacy designs or replacements due to its reliability.

MC33072PG Applications

The MC33072PG excels in:

• Active Filters & Signal Conditioning: Its GBWP and slew rate suit bandwidth-critical designs.
