TDA2005 is a class B dual audio power amplifier produced by Texas Instruments. It uses MULTIWATT package and is specifically designed for car radio applications. The amplifier provides a high current capability (up to 3.5 A) and can drive very low impedance loads (down to 1.6Ω).
The TDA2005 is a class‑B dual audio power amplifier in a MULTIWATT® package, designed for car‑radio applications. It can be used as a bridge amplifier (TDA2005M) or a stereo booster (TDA2005S) with programmable gain and bandwidth, offering high output power and built‑in protection features such as short‑circuit and over‑temperature safeguards.
The document lists absolute maximum ratings, typical electrical characteristics (supply voltage up to 18 V, output power up to 20 W in bridge mode), pin‑out diagrams, application schematics, thermal data and mechanical dimensions. It also includes ordering numbers and legal disclaimer information.
