2 × 8 W stereo BTL audio output amplifier

with DC volume control

Product specification

TDA7057AQ

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 TDA7057AQ is a stereo BTL output amplifier with DC

volume control. The device is designed for use in TVs and

monitors, but is also suitable for battery-fed portable

recorders and radios.

Missing Current Limiter (MCL)

A MCL protection circuit is built-in. The MCL circuit is

activated when the difference in current between the

output terminal of each amplifier exceeds 100 mA

(typical 300 mA). This level of 100 mA allows for

single-ended headphone applications.
