TDA7056B
FEATURES
DC volume control Few external components Mute mode Thermal protection Short-circuit proof No switch-on and switch-off clicks Good overall stability Low power consumption Low HF radiation ESD protected on all pins.
GENERAL DESCRIPTION
The TDA7056B 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).
