LM258ADT is an integrated differential amplifier from National Semiconductor. It can be used in various applications, from instrumentation and control systems, to amplifiers and filters. Its two main amplifiers, A and B, feature a gain of +1 and a current output of +1, making it suitable for numerous applications. The LM258ADT also offers excellent temperature stability and can be used in video and communications systems where good accuracy is essential. In this article, we will look at the application field and working principle of the LM258ADT.

Most linear amplifiers are designed to amplify a single input signal. The LM258ADT is a differential amplifier, which can be used to amplify two input signals in the same manner. Differential amplifiers have many advantages over single amplifiers, including increased noise immunity, higher accuracy, and improved stability. The LM258ADT can be used to provide fixed-gain amplification of AC, DC, or mixed signals. The LM258ADT is also particularly suitable for analog-to-digital conversion due to its wide input range.

The LM258ADT can also be used in instrumentation and control systems. It can be used to amplify signals in systems requiring accurate measurements of small physical variations, such as blood flow or pressure. The LM258ADT’s excellent temperature stability ensures good accuracy in these applications. It can also be used in data conditioning and signal buffering systems; it is especially suitable for isolation applications due to its high impedance inputs.

The LM258ADT has two gain stages: one with a gain of +1 and one with a current output of +1. The two-transistor stage ac-coupled input offers excellent noise rejection and can also be used to remove offsets. The gain of the LM258ADT can be adjusted using external resistors. The amplifier can also be configured as an inverting amplifier, phase-lag compensator, filter, or integrator by incorporating external components.

The LM258ADT is powered by a single power supply and has an operating voltage range from 4.75V to 15V. The device features a current consumption of 1.2mA and a maximum power dissipation of 500mW. It is available in an 8-pin DIP package. The LM258ADT has a maximum bandwidth of 3MHz and a typical slew rate of 0.2V/ns.

The LM258ADT can be used for a variety of applications, including instrumentation and control systems, amplifiers, filters, and analog-to-digital conversion. Its two-transistor ac-coupled input provides excellent noise immunity and its wide operating voltage range makes it suitable for use in many systems. The LM258ADT can be configured as an inverting amplifier, filter, or integrator, and its adjustable gain makes it suitable for numerous applications. The LM258ADT is an ideal choice for systems requiring precise measurements with excellent temperature stability.
