Product specification
Stereo BTL audio output amplifier with DC
volume control
TDA7053A
FEATURES
GENERAL DESCRIPTION
• DC volume control
The TDA7053A (2 × 1 W) and TDA7053AT (2 × 0.5 W) are
stereo BTL output amplifiers with DC volume control.
The devices are designed for use in TV and monitors, but
are also suitable for battery-fed portable recorders and
radios.
• Few external components
• Mute mode
• Thermal protection
• Short-circuit proof
Missing Current Limiter (MCL)
• No switch-on and switch-off clicks
• Good overall stability
• Low power consumption
• Low HF radiation
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
headphone applications (single-ended).
• ESD protected on all pins.
