SGS-THOMSON TDA2040 Datasheet
The TDA2040 is a monolithic integrated circuit in a Pentawatt® package designed for Class‑AB audio amplification. It delivers up to 22 W output power at 32 V supply, incorporates a patented short‑circuit protection system and a thermal shut‑down feature to keep the output transistors within their safe operating area.
The datasheet lists absolute maximum ratings, detailed electrical characteristics such as supply voltage, input bias current, output power, and gain, as well as mechanical dimensions of the package. It also includes typical application schematics, pin connections, and thermal data for designers integrating the device into audio equipment.
