TDA2005:Single BTL or dual SE output amplifier

The TDA2005 is a class B dual audio power amplifier in Multiwatt11 package specifically designed for car radio applications.

Power booster amplifiers can be easily designed using this device that provides a high current capability (up to 3.5 A) and can drive very low impedance loads (down to 1.6 Ω in stereo applications) obtaining an output power of more than 20 W (bridge configuration).

Key Features

  • High output power:
    • Po = 10 + 10 W @ RL = 2 Ω, THD = 10 %
    • Po = 20 W @ RL = 4 Ω , THD = 10 %.
  • Protection against:
    • Output DC and AC short circuit to ground
    • Overrating chip temperature
    • Load dump voltage surge
    • Fortuitous open ground
    • Very inductive loads
  • Loudspeaker protection during short circuit for one wire to ground
