TDA2005
TDA2005 20 W bridge/stereo amplifier for car radio 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 ■ Multiwatt11 Loudspeaker protection during short circuit for one wire to ground Description The TDA2005 is a class B dual audio power amplifier in Multiwatt11 package specifically designed for car radio applications. Table 1. 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).
