TDA8588AJ/R1CU

Product Summary

The TDA8588AJ/R1CU is an I2C-bus controlled 4×50Watt power amplifier and a multiple voltage regulator. The TDA8588AJ/R1CU 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-bus allows diagnostic information of each amplifier and its speaker to be read separately. Both front and both rear channel amplifiers can be configured independently in line driver mode with a gain of 20dB. The applications of the TDA8588AJ/R1CU include Boost amplifier and voltage regulator for car radios and CD/MD players.
