2 / 16 page 1998 Apr 07 2 Philips Semiconductors Product specification 2 × 8 W stereo BTL audio output amplifier with DC volume control TDA7057AQ 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 TDA7057AQ is a stereo BTL output amplifier with DC volume control. The device is designed for use in TVs and monitors, but is 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 single-ended headphone applications. QUICK REFERENCE DATA ORDERING INFORMATION SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX.
