Datasheet TDA7056A (NXP) - 2

NXP Semiconductors Product specification 3 W mono BTL audio amplifier with DC TDA7056AT volume control FEATURES GENERAL DESCRIPTION
• DC volume control The TDA7056AT is a mono Bridge-Tied Load (BTL) output • Few external components amplifier with DC volume control. It is designed for use in TVs and monitors, but is also suitable for battery-fed • Mute mode portable recorders and radios. The device is contained in • Thermal protection a 20-lead small outline package. • Short-circuit proof A Missing Current Limiter (MCL) is built in. The MCL circuit • No switch-on or switch-off clicks is activated when the difference in current between the • Good overall stability output terminal of each amplifier exceeds 100 mA (300 mA typ.). This level of 100 mA allows for • Low power consumption Single-Ended (SE) headphone applications. • Low HF radiation • ESD protected on all pins.
