TDA2009 amplifier circuit diagram bridge

| | , ,

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.

  • 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
The module has output current protection and thermal protection. This is the datasheet circuit which gives an excellent sound. The supply voltage required for this kit is 8 – 24V DC at 1 to 2 Amps. Maximum output power will only be obtained with a power supply of at least 20V and greater than 1.5 A, and using 4 ohm speakers.
