Product specificiation
3 W BTL mono audio output amplifier
with DC volume control
TDA7056A
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 TDA7056A is a mono BTL output amplifier with DC
volume control. It is designed for use in TV and monitors,
but also suitable for battery-fed portable recorders and
radios.
Missing Current Limiter (MCL)
A MCL protection circuits 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).
