TDA2040 IC Hi-Fi Audio Power Amplifier 40V 4A Pentawatt V
The TDA2040 is a monolithic integrated circuit in the Pentawatt V package, intended for use as an audio class-AB amplifier.
Typically, it provides 25 W output power into 4 Ω 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.
Features:
- Hi-Fi class-AB monolithic audio power amplifier in a compact Pentawatt V package.
- Wide supply flexibility can run from single or split (dual) supplies, making it convenient for many amplifier topologies.
- Built-in protection: automatic short-circuit/power-limiting system and thermal shutdown to improve robustness and protect the IC and output stage.
- Low harmonic & crossover distortion optimized for good audio fidelity, suitable for hi-fi speaker driving.
- High output current capability and robust output transistors suitable for driving low-impedance speakers and bridge configurations.
- Easy-to-use application circuits: reference application circuits, PCB layout recommendations and bridge/mono/single-supply examples are provided in the datasheet for quick building.
- Good noise and ripple rejection for cleaner sound with ordinary power supplies.
- Well suited for active crossovers, multiway speaker systems, and DIY hi-fi projects common in small amplifiers and powered speaker designs.
