Product specification

1 W BTL mono audio amplifier with DC

volume control

TDA7052A/AT

FEATURES

• DC volume control

• Few external components

• Mute mode

• Thermal protection

• Short-circuit proof

• No switch-on and off clicks

• Good overall stability

• Low power consumption

• Low HF radiation

• ESD protected on all pins

GENERAL DESCRIPTION

The TDA7052A/AT are mono BTL output amplifiers with

DC volume control. They are designed for use in TV and

monitors, but 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 headphone

applications (single-ended).
