2N4937 Application Field and Working Principle

The 2N4937 is a general-purpose, two-channel linear amplifier array manufactured by Texas Instruments. It is designed to provide either one differential input or two single-ended inputs and two single-ended outputs. The 2N4937 is used in applications ranging from low-power audio amplifiers to motor speed controllers. This article will provide an overview of the application fields, as well as a description of the working principle of the 2N4937.

Application Fields

Due to its low noise and high linearity, the 2N4937 is well-suited for many types of amplifier applications. These include:

• Low-power audio amplifiers
• High-efficiency drives for HDTVs
• Distortion-free power boosting for large power amplifiers
• Motor speed controllers

In addition to its use as an amplifier, the 2N4937 can be used as an oscillator to generate sinusoidal waveforms. This can be used, for example, to generate test signals for electronic audits. The 2N4937 can also be used in analog-to-digital converters and voltage-controlled oscillators.

Working Principle

The 2N4937 is a two-channel linear amplifier array that is designed to provide either one differential input or two single-ended inputs and two single-ended outputs. An integrated voltage regulator is included for improved stability and power efficiency. Its small package size allows for easy assembly and integration into other circuits.

The 2N4937 operates by using multiple transistors connected in a linear array, with each transistor amplifying a portion of the signal. As the signal flows through each transistor, the current is amplified before the signal is passed onto another transistor. This process is repeated until the output signal is amplified to the desired level.

The linearity of the amplifying chain is improved through the use of a feedback loop. This loop monitors the output signal and adjusts the operating conditions of the transistors for improved linearity and distortion reduction. This feedback loop is also used to maintain the 2N4937\'s specified working conditions even under varying input and output conditions.

The 2N4937\'s ability to provide excellent linearity and low noise makes it a popular choice for applications requiring distortion-free power amplification. Its integrated voltage regulator provides improved stability and power efficiency, making it well-suited for motor speed controllers and other applications requiring high-efficiency power amplification.
