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.
