STMicroelectronics TDA2003 10W Car Radio Audio Amplifier Datasheet
The TDA2003 is a 10 W car‑radio audio amplifier with a pin‑compatible design to the TDA2002. It offers high output current capability (up to 3.5 A) and low harmonic distortion, making it suitable for automotive audio applications. The device includes built‑in protection against short circuits, thermal overload, load‑dump voltage surges and open‑ground conditions.
Key specifications include a DC supply voltage rating of 28 V, an operating supply voltage of 18 V, a maximum power dissipation of 20 W, and an output power of up to 10 W into a 2 Ω load. The amplifier operates over a frequency range of 40 Hz to 15 kHz (‑3 dB) and features a junction‑case thermal resistance of 3 °C/W.
