The TDA2002 and TDA2002A are monolithic integrated circuits designed for class‑B audio power amplifier applications using low‑impedance loads. They are supplied in a 5‑pin power package (horizontal or vertical) and typically deliver 8 W at 14.4 V. The TDA2002A is electrically identical to the TDA2002 but lacks the over‑voltage (load‑dump) protection circuit.
The document provides electrical characteristics, typical performance curves, design considerations, and example application circuits, including thermal shutdown behavior and overload protection features for reliable operation in automotive and consumer audio environments.
| Peak Supply Voltage (50 ms) | 40 V |
|---|---|
| Supply Voltage | 28 V |
| Operating Supply Voltage | 18 V |
| Output Current (Repetitive) | 3.5 A |
| Output Current (Non‑Repetitive) | 4.5 A |
| Power Dissipation (Tc = 90 °C) | 15 W |
| Storage Temperature Range | -40 °C to 150 °C |
| Pin Soldering Temperature (10 s) | 260 °C |
| Thermal Resistance (junction‑to‑case, max) | 4 °C/W |
| Supply Voltage Range | 8 V to 18 V |
The device can tolerate up to 40 V for a 50 ms pulse.
Both devices have a thermal shutdown feature that reduces drive when the junction temperature exceeds the design threshold, limiting output power and supply current.
