INTEGRATED CIRCUITS DATA SHEET TDA7052A/AT 1 W BTL mono audio amplifier with DC volume control Product specification July 1994 Supersedes data of August 1991NXP Semiconductors Product specification 1 W BTL mono audio amplifier with DC TDA7052A/AT volume control FEATURES GENERAL DESCRIPTION DC volume control The TDA7052A/AT are mono BTL output amplifiers with DC volume control. They are designed for use in TV and Few external components monitors, but also suitable for battery-fed portable Mute mode recorders and radios. Thermal protection Missing Current Limiter (MCL) Short-circuit proof No switch-on and off clicks A MCL protection circuit is built-in. The MCL circuit is activated when the difference in current between the Good overall stability output terminal of each amplifier exceeds 100 mA (typical Low power consumption 300 mA). This level of 100 mA allows for headphone Low HF radiation applications (single-ended). ESD protected on all pins QUICK REFERENCE DATA SYMBOL PARAMETERS CONDITIONS MIN. TYP. MAX.
