The LM158J is a dual, wide-bandwidth operational amplifier that has been designed for use in applications including active filters, amplifiers, voltage followers and bus buffers. It contains two independent high-performance amplifiers with a wide operating temperature range ( -55°C to 150°C) and an excellent gain bandwidth of 1MHz.

The LM158J operates off of any supply voltage from 3.5V up to 14V. The high gain and low offset voltage of LM158J makes it ideal for circuit designs that require precise high-speed signals. It has high CMRR, low input noise and low power consumption making it a good choice for many audio applications.

The LM158J can be used in a variety of applications including active filters, amplifiers, voltage followers and bus buffers. It has a single ended input and differential outputs that can drive up to 700mA. It also features short-circuit protection and anti-saturation circuitry.

Instrumentation, OP amps, and buffer amps are one of the most popular applications for the LM158J due to its high gain and excellent gain bandwidth. The LM158J can be operated in both inverting and non-inverting mode, making it suitable for both constant gain and dynamic gain control applications.

The working principle of the LM158J is simple. It is an integrated circuit containing two independent, high-performance operational amplifiers. These amplifiers have a two-fold purpose: the first is to amplify and condition an electrical signal, and the second is to buffer the output of the amplifier to reduce distortion and improve signal accuracy. The LM158J operates off of a supply voltage of 3.5V to 14V, although the supply voltage must not exceed the output voltage range of the LM158J.

The amplifiers are designed to amplify a small AC voltage signal into a large AC voltage signal. The input stage uses an input impedance of several hundred kilohms, while the output stage uses an output impedance of several hundred ohms. The amplification occurs in the gain cell, which consists of two transistors that convert the small AC input signal into a large AC output signal. The output stage also includes two transistors that regulate the output voltage and send it to the load.

The LM158J is a versatile dual-channel operational amplifier widely used in a variety of applications. Its operation is based on simple amplification and buffering of an electrical signal, with a wide operating temperature range, a high gain and low offset, high CMRR, low input noise and low power consumption making it a good choice for many audio applications. Its single-ended input and differential output, short-circuit protection and anti-saturation circuitry make it suitable for both constant gain and dynamic gain control applications.
