2 / 16 page 1997 Jul 15 2 Philips Semiconductors Product specification Stereo BTL audio output amplifier with DC volume control TDA7053A FEATURES • DC volume control • Few external components • Mute mode • Thermal protection • Short-circuit proof • No switch-on and switch-off clicks • Good overall stability • Low power consumption • Low HF radiation • ESD protected on all pins. GENERAL DESCRIPTION The TDA7053A (2 × 1 W) and TDA7053AT (2 × 0.5 W) are stereo BTL output amplifiers with DC volume control. The devices are designed for use in TV and monitors, but are also suitable for battery-fed portable recorders and radios. Missing Current Limiter (MCL) 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). QUICK REFERENCE DATA ORDERING INFORMATION SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX.
