What is TDA7721TR

What is TDA7721TR

‌The TDA7721TR is an integrated circuit produced by STMicroelectronics (ST) and is mainly used for audio signal processing. It is packaged in TSSOP-28 and is suitable for car audio and other audio applications.

Audio Special Purpose ICs are integrated circuits that can store and control voice playback. They convert voice signals into digital signals through sampling, store them in the IC's ROM, and then restore the digital signals in the ROM to voice signals through circuits. The output methods of Audio Special Purpose ICs are divided into two categories, one is PWM output method and the other is DAC output method. The PWM output volume cannot be continuously adjusted and cannot be connected to ordinary power amplifiers, while DAC is amplified by internal EQ, the sound is continuously adjustable, can be digitally controlled and adjusted, and can be connected to external power amplifiers.
