TECHNICAL DATA
5 W MONO BTL AUDIO AMPLIFIER WITH DC VOLUME CONTROL
GENERAL DESCRIPTION
The KKA7056B 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).
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.

Measured at a THD of 10%. The maximum output power
is limited by the maximum power dissipation and the
maximum available output current.
