The TDA2009 amplifier circuit diagram is a bridge audio power amplifier hi-fi in multiwatt package, developed especially for high quality stereo applications. This application is the bridge amplification, where the two tda2009 internal amplifiers are used. The good thing about the TDA series of integrated circuits is that they are electronic components that are easy to find in electronics stores.
The TDA2009 is a class AB stereo audio power amplifier that contains two identical amplifiers capable of delivering 10W per channel.
It is designed for quality Hi-Fi stereo application which is easy to construct and has a mini mum need of external components.
The TDA2009A is a class AB dual Hi-Fi Audio power amplifier assembled in MULTIWATT® package, specially designed for stereo application as Hi-Fi and music centers
- High output power (10 + 10w min. @ d = 1%)
- AC short circuit protection
- High current capability (up to 3.5a)
- Space and cost saving : very low number of external components and simple mounting thanks to the multiwatt® package.
- Thermal overload protection
