STMicroelectronics TDA7293V DMOS Class AB Audio Amplifier - 100V
STMicroelectronics TDA7293V DMOS class AB audio amplifier IC. 100W output, ±12-50V range, low noise & distortion for Hi-Fi systems.
The STMicroelectronics TDA7293V is a premium DMOS class AB audio amplifier designed for the high-fidelity audio market, offering exceptional power output and sound quality. Housed in a robust 15-pin Multiwatt package, it is engineered to serve as the core component in demanding home audio applications. It is an ideal solution for constructing high-performance home stereo systems, self-powered loudspeakers, and top-tier television audio systems, delivering clean, powerful sound.
A key advantage of the TDA7293V is its wide operating voltage range, from ±12V to ±50V, combined with high output current capability. This allows the amplifier to deliver its maximum rated power into a variety of load impedances, including both 4ohm and 8ohm speakers. It can supply a high output power of 100W into an 8ohm load, ensuring ample volume and dynamic range for immersive listening experiences. The design incorporates advanced Multipower BCD technology for efficient operation.
To enhance user experience and system integration, the amplifier features built-in muting and stand-by functions. These include a turn-on delay within the muting circuit, which effectively eliminates annoying switch-on and switch-off noises for seamless, quiet operation, especially useful in remote-controlled systems. For applications requiring even greater power, several TDA7293V devices can be connected in parallel mode using pin 11, enabling the delivery of high output power to very low impedance loads when system thermal management is optimised.
The audio performance is characterised by very low distortion and exceptionally low noise levels, preserving the integrity of the original audio signal. Protection features include short-circuit protection (when no input signal is applied) for increased reliability. The device operates reliably within an ambient temperature range of 0°C to 70°C and offers a swift 10V/μs slew rate for accurate transient response. This combination
