GENERAL DESCRIPTION
The TDA7056AT is a mono Bridge-Tied Load (BTL) output amplifier with DC volume control. It is designed for use in TVs and monitors, but is also suitable for battery-fed portable recorders and radios. The device is contained in a 20-lead small outline package.
A Missing Current Limiter (MCL) is built in. The MCL circuit is activated when the difference in current between the output terminal of each amplifier exceeds 100 m A (300 m A typ.). This level of 100 m A allows for Single-Ended (SE) headphone applications.
