Product specification
Mono BTL audio amplifier with DC volume
control
TDA7052B
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 TDA7052B and TDA7052BT are 1 W and 0.5 W mono
Bridge-Tied Load (BTL) output amplifiers with DC volume
control.
They have been designed for use in TV and monitors, but
are also suitable for use in battery-fed portable recorders
and radios.
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).
