KKA7056B Datasheet | Kodenshi AUK Group

DESCRIPTION The KKA7056B 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 m A (300 m A typ.). This level of 100 m A allows for headphone applications (single-ended).
