NXP 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 • Few external components DC volume control. They are designed for use in TV and monitors, but also suitable for battery-fed portable • Mute mode recorders and radios. • 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 • Good overall stability activated when the difference in current between the 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
