3 W BTL mono audio output
amplifier with DC volume control
Product specificiation July 1994 NXP Semiconductors Product specificiation 3 W BTL mono audio output amplifier with
DC volume control TDA7056A FEATURES GENERAL DESCRIPTION • DC volume control 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. • Few external components
• Mute mode
• Thermal protection
• Short-circuit proof Missing Current Limiter (MCL) • No switch-on and off clicks 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). • Good overall stability
• Low power consumption
• Low HF radiation
• ESD protected on all pins.
