Description
The TDA7056AT is a mono BTL (Bridge-Tied Load) audio amplifier from NXP Semiconductors, designed for low-voltage applications. Key features:
- Output Power: 1.4W (typical) into 8Ω at 6V.
- Operating Voltage: 3V to 18V, making it suitable for battery-powered devices.
- BTL Configuration: Eliminates the need for an output capacitor, saving space and cost.
- Low Standby Current: ~50nA, enhancing energy efficiency.
- Thermal Protection: Built-in safeguards against overheating.
- Minimal External Components: Requires few external parts, simplifying design.
Commonly used in portable radios, TVs, and small audio systems, the TDA7056AT is housed in an 8-pin DIP or SO package. Its fixed gain (40dB) reduces design complexity, while its robust performance suits cost-sensitive, compact applications.
For detailed specs, refer to the datasheet.
