2 / 9 page July 1994 2 Philips Semiconductors Product specificiation 3 W BTL mono audio output amplifier with DC volume control TDA7056A FEATURES • DC volume control • Few external components • Mute mode • Thermal protection • Short-circuit proof • No switch-on and off clicks • Good overall stability • Low power consumption • Low HF radiation • ESD protected on all pins. GENERAL DESCRIPTION The TDA7056A is a mono BTL output amplifier with DC volume control. It is designed for use in TV and monitors, but also suitable for battery-fed portable recorders and radios. Missing Current Limiter (MCL) A MCL protection circuits 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). QUICK REFERENCE DATA ORDERING INFORMATION Note 1. SOT110-1; 1996 August 21. SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX.
