TDA7801SMTR is a class AB mono audio power amplifier which is designed for the use of car radio audio system. Based on its rapid and stable start-up characteristic and its high signal-to-noise ratio, it is an ideal choice for the use of car radio audio system. It features an EIA--standard 8-pin microphone, minimal external components and its good sound quality, it is a perfect choice for the use of car radio audio system.
The TDA7801SMTR is a single-quadrant, single-ended, Class AB operation audio amplifier. It is a power amplifier that amplifies the audio signal from the microphone to the speaker via a voltage gain. In this configuration, the source is placed close to the amplifier and the power supply is connected to the amplifier section.
The TDA7801SMTR circuit is based on a classic voltage-gain amplifier configuration using bipolar transistors such as pnp/npn pair. The signal first passes through current-mirror stage to reduce the output voltage offset and increase the linearity of the circuit. Then, it will be amplified by the amplifier stage, controlled by two complementary emitter follower. At last, it will be sent to the speaker.
The output power of TDA7801SMTR is up to 4W.The power supply range of TDA7801SMTR is 7V – 14V. This amplifier can deliver a peak of 5W per channel. The thd+n (total harmonic distortion and noise) is lower than 0.1%, which can guarantee clean and clear sound without distortion. Moreover, the TDA7801SMTR has a good frequency response range, from 15Hz to 30KHz. The single-ended gain range of TDA7801SMTR is from 25dB to 40dB.
The application field of TDA7801SMTR is broadly range, from car audio system, to audio system of TV and home audio. Actually, the working principle of TDA7801SMTR is similar to other monolithic audio power amplifiers. TDA7801SMTR is built on the classic voltage-gain amplifier principle. It uses two complementary emitter followers to control the output power. The signal passes through the current-mirror stage and gets amplified by the amplifier stage. With quality components, and careful circuit design, TDA7801SMTR is capable of delivering excellent sound quality.
With its high power, low electromagnetic interference, low distortion, and wide frequency response, TDA7801SMTR is suitable for car audio system, TV audio system and other home audio system. Its compact form factor and simple circuit design are great for applications where space is limited. Thus, TDA7801SMTR is an ideal choice for audio power amplification in various fields.
