TDA7293 is the same conversion rate as TDA7294, however, it comes with a larger voltage supply range, and is the most powerful Dual 50 volt DC power supply which gives the user a greater dynamic range and greater output power. A load of 8 ohms with a 40V dual power source may generate an average power output of 100W. However, if the voltage is increased to 50V, or the load is decreased to 4 ohms, then the output power will rise, as per the TDA7293 specifications. Dual 28V AC voltage can be chosen when selecting an appropriate transformer, leading to an approximate 40V voltage after the rectification process and filtering. Of course, the voltage may be increased. Because of the variations of the grid voltage, it is recommended to lower than 50V, which allows the circuit to function in a more stable manner. Today, easybom will introduce the differences between them to help you understand them.
What is TDA7293 audio amplifier?
TDA7293 amplifier is a single-chip integrated circuit within the Multiwatt15 package that is designed to be used in the audio class amplifier within Hi-Fi field-based applications, like home stereos self-powered loudspeakers, and Topclass TV. Because of the broad voltage range and capacity to output high currents, it can deliver the maximum power to both the 4 and 8 loads. The built-in muting feature with turn-on delay makes it easier to control the remote operation by avoiding on-off switch noises. Parallel mode is achievable by connecting multiple devices and making use of pin11. High output power can be supplied to loads with low impedance and thus maximizing the heat dissipation capacity of the system.
What is TDA7294 audio amplifier?
The TDA7294 amplifier is an audio amp. It is a single-chip integrated circuit that is a Multiwatt15 package. It was intended to be used as an amplifier of class AB in the field of audio. Due to the wide voltage range and the ability to produce high current output that it is able to provide the most power to 4Ω and 8Ω loads even in the event of an issue with the regulation of the source and also the capability to block high supply voltage. The built-in muting feature with turn-on delay makes it easier to use the remote's operation by eliminating the sounds of turning off.
