TDA749213TR is a versatile, high performance, wide power supply range wideband audio linear amplifier. As an audio linear amplifier, the TDA749213TR can be used in a variety of applications, including audio power amplifiers, driver stages for CD and DVD players, as well as for digital-to-analog converters. The TDA749213TR has a wide power supply range from 3.5 V to 17 V and can deliver up to 3.5 W output power. The TDA749213TR also offers high SNR, which provides superior audio quality.

The TDA749213TR is designed with a non-overloadable WMOS voice-coil and single-ended class-D outputs. It enables low distortion and wide signal bandwidth. The TDA749213TR comes with a gain adjustable control, so that the signal level can be adjusted according to the application requirement. The TDA749213TR includes thermal protection as well as over-voltage and over-temperature protection, allowing it to operate safely in a wide range of conditions.

The working principle of the TDA749213TR is that it takes the input audio signal, amplifies it and then outputs it at the device’s maximum power. The TDA749213TR uses a pulse-width modulation (PWM) technique to produce the amplified output. In PWM, the input signal is fed into an encoding block, which separates the signal into two parts. The first part is the signal’s DC component and the second is the signal’s AC component. The DC component is then passed through an active filter and then fed into the pulse width modulation circuit. The PWM circuit will then switch the output audio signal on and off at the audio signal’s frequency. This in turn will produce the amplified signal, which can then be used for applications.

The TDA749213TR is a highly efficient and reliable audio linear amplifier that is ideal for various audio applications. Its wide power supply range and adjustable gain allow it to be used in a variety of conditions and scenarios. Its high SNR and non-overloadable WMOS voice-coil make it ideal for high quality audio applications. The TDA749213TR is an excellent choice for audio applications that require high performance and no compromise on audio quality.
