Product specification

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).
