Philips Semiconductors Product specification 1 W BTL mono audio amplifier with DC TDA7052A/AT volume control FUNCTIONAL DESCRIPTION Thus a reduced power supply with smaller capacitors can be used which results in cost savings. The TDA7052A/AT are mono BTL output amplifiers with For portable applications there is a trend to decrease the DC volume control, designed for use in TV and monitors supply voltage, resulting in a reduction of output power at but also suitable for battery fed portable record
