The TDA8946J/N1,112 is a digital audio amplifier that utilises pulse-width modulated output to deliver sound. It has a wide range of applications, from home entertainment systems to professional sound reinforcement, and is relatively easy to implement in OEM systems too. The main feature of the TDA8946J/N1,112 is its low distortion, high efficiency and wide bandwidth.

The TDA8946J/N1,112 is considered to be a Linear-Amplifier-Audio, due to its use of a direct amplifier that employs a linear transfer characteristic. It amplifies audio signals from low voltage levels up to a level sufficient for switching transistors. The low distortion is achieved through a combination of a few different design elements including low noise components, capacitor-filtered power supplies, EMI shielding and multiple output stages.

The TDA8946J/N1,112 operates with a compact and efficient digital pulse-width modulated output. The PWM method used by the amplifier delivers an effective efficient amplification of the audio signal while minimising the circuit complexity. This allows the amplifier to achieve a greater dynamic range than what would be possible using conventional linear amplifiers.

The circuit schematic for the TDA8946J/N1,112 is fairly simple, with a low voltage -/+ 15V supply input and a +5V reference input. The amplifier uses a push-pull output stage for amplification of the audio signals, which is followed by a low-pass filter for the output. The amplifier is compliant with most commonly used audio formats such as Dolby Digital and DTS thanks to the low noise and low distortion design.

Overall, the TDA8946J/N1,112 is an ideal choice for a wide range of audio systems, from home entertainment to professional sound systems. It is an economical choice due to its low complexity, low noise and low distortion design, and it can be easily interfaced with most commonly used audio formats. This makes it an ideal choice for OEM applications and a great way to improve the audio performance of any system.
