Key Features

  • High Output Power: Up to 20 W in bridge configuration and 10 + 10 W in stereo configuration at THD = 10%.
  • Protection Features: Protection against output DC and AC short circuit to ground, overrating chip temperature, load dump voltage surge, fortuitous open ground, very inductive loads, and loudspeaker protection during short circuit for one wire to ground.
  • High Current Capability: Up to 3.5 A, enabling the drive of very low impedance loads (down to 1.6 Ω in stereo applications).
  • Efficiency: High efficiency in both bridge and stereo configurations.
  • Supply Voltage Rejection: Good supply voltage rejection ratio to minimize noise.

Applications

The TDA2005R is primarily designed for car radio applications, making it an ideal choice for automotive audio systems. It can also be used in other applications requiring high power audio amplification, such as power booster amplifiers and loudspeaker systems.
