Description
The TDA2040 is a monolithic integrated circuit in the Pentawatt package, intended for use as an audio class-AB amplifier. Typically, it provides 25 W output power into 4 O with THD = 0.5% at VS = 34 V. The TDA2040 provides high output current and has very low harmonic and crossover distortion. Furthermore, the device incorporates a patented short-circuit protection system comprising an arrangement for automatically limiting the dissipated power so as to keep the operating point of the output transistors within their safe operating range. A thermal shutdown system is also included.
- Wide-range supply voltage, up to 40 V
- Single or split power supply
- Short-circuit protection to ground
- Thermal shutdown
- PO = 25 W @ THD = 0.5%, VS = ±17 V, RL= 4 O
- PO = 30 W @ THD =10%, VS = ±17 V, RL = 4 O
