Part Number: TDA7293
Function: 120V – 100W DMOS AUDIO AMPLIFIER WITH MUTE/ST-BY
Package: Multiwatt15V Type
Manufacturer: ST Microelectronics
A DMOS (Double-Diffused Metal-Oxide-Semiconductor) audio amplifier is a type of power amplifier specifically designed for audio applications. DMOS amplifiers utilize DMOS transistors, which are power MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors), to deliver high-power, high-fidelity amplification for audio signals.
1. High Power Handling: DMOS transistors are capable of handling high power levels, allowing DMOS audio amplifiers to deliver substantial output power.
2. Low Distortion: DMOS transistors exhibit low levels of distortion, contributing to high-fidelity audio reproduction.
3. Efficient Power Conversion: DMOS transistors have a low on-resistance and can operate at high efficiency, which reduces power dissipation and improves overall energy efficiency.
4. Robustness: DMOS transistors are designed to withstand high voltage and current stresses, making DMOS audio amplifiers suitable for demanding audio applications.
The TDA7293 is a monolithic integrated circuit in Multiwatt15 package, intended for use as audio class AB amplifier in Hi-Fi field applications, such as home stereo, self powered loudspeakers and Topclass TV. Thanks to the wide voltage range and to the high output current capability it is able to supply the highest power into both 4-Ω and 8-Ω loads. The built-in muting function with turn-on delay simplifies the remote operation avoiding on-off switching noises. […]
