5 W mono BTL audio amplifier with DC
volume control
Product specification
TDA7056B
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 TDA7056B is a mono Bridge-Tied Load (BTL) output
amplifier with DC volume control.
It is designed for use in TV and monitors, but is also
suitable for battery-fed portable recorders and radios.
The device is contained in a 9-pin medium power
package.
A Missing Current Limiter (MCL) is built in. The MCL circuit
is activated when the difference in current between the
output terminal of each amplifier exceeds 100 mA
(300 mA typ.). This level of 100 mA allows for headphone
applications (single-ended).
