AS1702V-T Application Field and Working Principle

The AS1702V-T device is a versatile amplifier which is ideal for use in Linear-Amplifiers-Audio applications. This device is useful for providing medium to high power amplification and is well suited for applications where power efficiency and small size is priority. It has the capability to achieve high power and efficiency when used for audio amplification.

The AS1702V-T consists of two amplifier stages, an input amplifier and output amplifier, each being capable of providing up to 200W of power. The input amplifier consists of an input resistor and a corresponding output resistor, and the output amplifier consists of a single output stage transistor, coupled with an output DC blocking capacitor. The input and output of the input amplifier are connected to the output connections, so that they can feed the output amplifier with the required power. The input stage of the amplifier is not directly connected to the output stage, but the inputs are connected to the gate of the output transistor in order to allow the necessary voltage gain. This setup is used to ensure that the amplifier is stable, while not increasing the complexity of the design.

In operation, when an audio signal is provided to the input of the amplifier, the input resistor and output resistor together form a voltage divider, which reduces the noise level of the input signal. The amplified signal then passes through the output transistor which is biased with a reverse-biased base-emitter junction. This setup allows for efficient power conversion, providing the output amplifier with a high level of output power with minimal amount of heat dissipated. This process is complemented by the proportional feedback from the output capacitor which helps to stabilize the DC operating point of the output transistor, ensuring a high level of accuracy and performance.

The AS1702V-T also incorporates control circuitry which enables the user to set the gain, tone and distortion control for the amplifier. This control circuit provides fine tuning for the end user, allowing them to adjust the frequency response and distortion to ensure the best overall performance of the amplifier. This control circuitry also ensures that the amplifier remains stable, in line with the initial design parameters, while also maintaining the desired frequency and distortion levels.

In summary, the AS1702V-T is a versatile and efficient amplifier which is particularly well suited for use in Linear-Amplifiers-Audio applications. It has the capability to achieve high levels of power efficiency and accurate performance. The control circuitry provides the user with the ability to fine tune the sound quality and distortion of the amplifier, while maintaining stability and accuracy. Its combination of features makes it the perfect choice for applications which require power efficiency, small size and accurate performance.
