TDA7454 - 4 x 35W HIGH EFFICIENCY QUAD BRIDGE CAR RADIO AMPLIFIER

Description

The TDA7454 is a new BCD technology QUAD BRIDGE type of car radio amplifier in Flexiwatt25 package specially intended for car radio applications.

Features

  • its superior efficiency performance coming from the internal exclusive structure, makes it the most suitable device to simplify the thermal management in high power sets. The dissipated output power under average listening condition is in fact reduced up to 50% when compared to the level provided by conventional class AB solutions. 6 VCC1 20 7 VCC2 - VCC 8 RIGHT FRONT 9+ S-GND 13 5+ 2 RIGHT REAR 319 - 18 LEFT FRONT 17 + TAB 1 21 + 24 LEFT REAR 23 - D94AU172C 1/13 TDA7454.
