AN5273

AN 5273 is an audio linear amplifier playing a vital role in regulating audio signals. It is a specially designed operational amplifier with differential inputs and a single-ended output. The amplifier provides a wide voltage gain range, low noise, and excellent power supply rejection. It also provides distortion-free dynamic range by offering excellent performance. It is widely used in audio devices, such as portable amplifiers, multimedia systems, audio equalizers, public address systems, and other audio systems.

AN 5273 can effectively operate with any power supply. It requires very little power to operate, making it an economical and efficient audio amplifier. It also supports the incorporation of DC and AC audio signals, making it suitable for use with a wide variety of applications. With its small size and light weight, AN 5273 can also easily be integrated with other audio devices, making it a perfect fit for portable and mini audio projects.

The working principle of AN 5273 is based on a single high-performance op-amp circuit with differential inputs and a single-ended output. The audio signal is fed into the differential inputs, which consists of a pair of transistors connected in an emitter-coupled-pair topology. The high-gain op-amp within the circuit amplifies the differential signal; the amplified signal is then fed to the single-ended output, which is then delivered to the load. The gain of the amplifier is determined by the ratio of the load resistance to the feedback resistor. The feedback resistor determines the mode of operation; Class A or Class AB. Class A mode has a lower distortion while Class AB mode provides higher power efficiency.

AN 5273 is a dependable and effective audio amplifier, providing a bipolar input and output that is unequaled in any audio circuit available. It provides a filterless voltage gain structure and boasts an extremely low distortion. Its low noise and low power consumption coupled with its simple design make it an ideal choice for a wide variety of audio applications. It can be used for both analog and digital audio systems.
