... OUT1 13 positive output 1 FUNCTIONAL DESCRIPTION The TDA7057AQ is a stereo output amplifier with two DC volume control stages. The device is designed for TVs and monitors, but is also suitable for battery-fed portable recorders and radios. In conventional DC volume control circuits the control or input stage is AC-coupled to the output stage via external capacitors to keep the offset voltage low ...
