The MC1458ID is a monolithic integrated dual operational amplifier that is used in a variety of applications such as linear amplifiers, instrumentation, and buffers. This article will provide an overview of its working principle and discuss the various application fields of MC1458ID.

The MC1458ID was developed by the Signetics Corporation and it is the first integrated operational amplifier on the market. It is a very popular device due to its high performance, low noise, and good stability in both single and dual configurations. The MC1458ID can provide up to 20 dB of gain and up to 0.2 V of output noise at 1 kHz. It has a wideband response with a −3 dB bandwidth of 18 MHz and low offset voltage.

The MC1458ID can be used in a variety of applications. It is used as a linear amplifier in audio, video, and power amplifiers, as well as in other circuits such as filters and low-frequency oscillators. It is also used in instrumentation circuits, including audio and video signal conditioners, sample and hold circuits, and other applications where precise levels of gain and stability are required.

In addition, the MC1458ID can be used as a buffer amplifier, providing an impedance buffer between a high and low impedance circuit. This is useful in applications such as isolating an input signal from a high impedance source, or providing an output signal with a constant level of impedance. The MC1458ID can also be used in radio-frequency (RF) amplifiers, providing amplification with good linearity and low noise.

The MC1458ID operates on a basic principle known as complimentary symmetry. This is a technique that uses both NPN and PNP transistors to create a symmetric circuit, allowing both positive and negative signals to be amplified with accurate and precise levels of gain. In addition, the MC1458ID has two stages, an input stage and a feedback stage, in order to improve the overall stability of the device.

The MC1458ID is an excellent choice for a wide range of applications due to its high performance, low noise, and good stability. It is a versatile device that is used in linear amplifiers, instrumentation, and buffers. It can provide up to 20 dB of gain and up to 0.2 V of output noise at 1 kHz and has a wideband response with a −3 dB bandwidth of 18 MHz and low offset voltage. By utilizing its complimentary symmetry design and two-stage feedback, the MC1458ID provides excellent performance in a variety of applications.
