TDA7057AQ - NXP

TDA7057AQ 2 x 8 W stereo BTL audio amplifier

TDA7057AQ 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 o.
