Product specification
Supersedes data of August 1991 July 1994 NXP Semiconductors Product specification 1 W BTL mono audio amplifier with DC
volume control TDA7052A/AT 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
monitors, but also suitable for battery-fed portable
recorders and radios. • Few external components
• Mute mode
• Thermal protection
• Short-circuit proof Missing Current Limiter (MCL) • 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
output terminal of each amplifier exceeds 100 mA (typical
300 mA). This level of 100 mA allows for headphone
applications (single-ended). • Good overall stability
• Low power consumption
• Low HF radiation
• ESD protected on all pins
