TDA7056B/N1,112 Description

The TDA7056B/N1,112 is a mono Bridge-Tied Load (BTL) output amplifier with DC volume control. It is designed for use in TV and monitors but is also suitable for battery-fed portable recorders and radios. The device is contained in a 9-pin medium power 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 mA (300 mA typ.). This level of 100 mA allows for headphone applications (single-ended).
