TDA2005S Description

Short technical summary and product information.

The TDA2005S from ST is a class B dual audio power amplifier IC housed in a MULTIWATT11 package, specifically engineered for automotive radio applications. This device is capable of delivering high output power, with ratings up to 20W into a 4Ω load with 1% distortion, and 18W into a 3.2Ω load with 10% distortion.

Key features include comprehensive protection against output short circuits to ground, overheating, load dump voltage surges, fortuitous open grounds, and very inductive loads. It also provides loudspeaker protection during short circuits. The TDA2005S offers flexibility in use, supporting bridge or stereo booster amplifier configurations with programmable gain and bandwidth. Its design emphasizes space and cost savings, requiring a minimal number of external components and a simple mounting system.

Electrical characteristics include an operating supply voltage range of 8V to 18V, with a maximum DC supply voltage of 28V and a peak supply voltage of 40V for 50ms. The device can handle output peak currents up to 4.5A non-repetitively and 3.5A repetitively. The thermal resistance from junction to case is a low 3°C/W, facilitating efficient heat dissipation.

This amplifier is suitable for power booster applications in car radios, music players, and other audio systems requiring significant power output and reliability. The MULTIWATT11 package is designed for through-hole mounting.
