TDA1557Q ,Stereo Car Amplifier , 2 x 22W Output, BTL Configuration

The TDA1557Q is a powerful, compact, and highly efficient Class-B output amplifier specifically designed for stereo car radio applications. With a configuration of two 22W amplifiers in BTL (Bridge-Tied Load), it is optimized to deliver high output power and superior audio quality while ensuring the protection of the connected speakers. This integrated circuit is protected against short circuits and can withstand reverse polarity, providing enhanced safety in automotive environments.

The TDA1557Q amplifier also includes advanced protection mechanisms such as load dump protection, speaker protection, and AC/DC short-circuit protection. Built with a mute/standby switch and low offset voltage, it offers high reliability and stability in car audio applications. Ideal for situations requiring low harmonic distortion and minimal external components, the TDA1557Q ensures high fidelity audio reproduction with minimal installation complexity.

Key Features :

• High Output Power: Delivers up to 22W per channel in BTL configuration, suitable for car radio applications requiring robust audio performance.
• Speaker Protection: Incorporates built-in protection for speakers against DC voltage and load dump events.
• Thermal and Overload Protection: Features thermal and short-circuit protection to enhance device reliability and longevity.
