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).
