Philips Semiconductors Product speciﬁcation

Stereo BTL audio output ampliﬁer with DC

volume control TDA7053A

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 TDA7053A (2 ×1 W) and TDA7053AT (2 ×0.5 W) are

stereo BTL output amplifiers with DC volume control.

The devices are designed for use in TV and monitors, but

are 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).
