The document describes the TDA1512A and TDA1512AQ, which are 12 to 20 W high-fidelity audio power amplifiers. These monolithic integrated circuits are specifically designed for use with asymmetrical power supplies in mains-fed apparatus.
Key features include thermal protection, low intermodulation distortion, a built-in output current limiter, and an output stage with low cross-over distortion. The devices are available in Single In-Line (SIL) plastic power packages.
| Output power (typical) | 13 W at Vp=25V, RL=4Ω; 7W at Vp=25V, RL=8Ω |
|---|---|
| Supply voltage range | 16 to 35 V |
| Total quiescent current (typical) | 65 mA at Vp = 25 V |
| Closed-loop voltage gain (typical) | 30 dB |
| Signal-to-noise ratio (typical) | 72 dB at Py = 50 mW |
The typical sine-wave output power is 13 W with a 4Ω load and 7W with an 8Ω load at a supply voltage of 25 V.
The supply voltage range is between 16 V and 35 V.
