TDA7052B;TDA7052BT
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).
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.
