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).
