ON Semiconductor MC33172P General-Purpose Operational Amplifiers

The MC33172P from ON Semiconductor is a versatile and high-performance operational amplifier that is designed to address a wide range of applications in the industrial, automotive, and consumer electronics sectors. This operational amplifier (op-amp) is known for its low-power consumption and wide bandwidth, making it an ideal choice for analog signal conditioning, filtering, and amplification tasks.

The MC33172P is a dual operational amplifier, which means it contains two independent op-amps in a single package. This feature allows for more compact circuit designs and can reduce the overall parts count in many applications. It operates over a wide range of power supply voltages, from +3V to +36V, or dual supplies of ±1.5V to ±18V, providing designers with flexibility in various circuit configurations.

One of the key attributes of the MC33172P is its low input bias current, which minimizes errors in high-impedance circuits. Additionally, it boasts a low input offset voltage, which is crucial for precision applications where signal integrity is paramount. The device also offers a high slew rate, ensuring that signals are amplified without distortion, even at higher frequencies.

With a large output voltage swing, the MC33172P can drive a wide range of loads, making it suitable for audio applications, sensor amplification, and active filters. The device's unity-gain bandwidth of 4.5MHz provides ample bandwidth for many moderate-speed applications, while its stable operation for gains as low as one (unity gain) makes it a reliable choice for closed-loop systems.

ON Semiconductor's commitment to quality is evident in the MC33172P's robust design, which includes short-circuit protection and thermal overload protection. This ensures long-term reliability and stability in the field, even under stressful conditions. The MC33172P is available in a DIP-8 package, which is well-suited for prototyping as well as for mass production.

In summary, the MC33172P operational amplifier from ON Semiconductor is a high-performance, cost-effective solution for a multitude of electronic applications. Its combination of low power, wide bandwidth, and operational stability makes it a go-to component for engineers and designers seeking to optimize their analog circuitry.
