TDA7056 3W mono channel output allows a single integrated circuit used in two pieces. 3 … 18V DC supply voltj application has been run by 3 AA batteries.
TDA7056 3Watt BTL audio amplifier
The TDA7056 is a mono output amplifier, designed for battery-fed portable radios and mains-fed equipment such as television. For space reasons there is a trend to decrease the number of external components. For portable applications there is also a trend to decrease the number of battery cells, but still a reasonable output power is required.
The TDA7056 fulfills both of these requirements. It needs no peripheral components, because it makes use of the Bridge-Tied-Load (BTL) principle. Consequently it has, at the same supply voltage, a higher output power compared to a conventional Single Ended output stage.
