GENERAL DESCRIPTION
The TDA7052B and TDA7052BT are 1 W and 0.5 W mono Bridge-Tied Load (BTL) output amplifiers with DC volume control. They have been designed for use in TV and monitors, but are also suitable for use in battery-fed portable recorders and radios.
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 headphone applications (single-ended).
