Product Summary

The TDA8589AJ is a multiple voltage regulator. The TDA8589AJ has a complementary quad audio power amplifier that uses BCDMOS technology. It contains four amplifiers configured in Bridge Tied Load (BTL) to drive speakers for front and rear left and right channels. The I2C-busallowsdiagnosticinformationofeachamplifierand its speaker to be read separately. The applications of it are Boost amplifier and voltage regulator for car radios and CD/MD players.
