TDA7297D

Overview

The TDA7297D is a dual bridge amplifier IC designed for Home Audio, Plasma TV, and LCD TV applications. It operates on a wide supply voltage range of 6.5V to 18V. The device delivers an output power of 10W per channel at THD=10% with an 8Ω load and 13V supply. It utilizes BI20II technology and features internally fixed gain, requiring no SVR capacitor, bootstrap components, or Boucherot cells. Protection mechanisms include short circuit and thermal overload safeguards.

Feature Summary

• Dual bridge amplifier architecture optimized for television and home audio systems
• Integrated protection against short circuits and thermal overload conditions
• Supports stand-by and mute functions to manage operational states
• Minimizes external component requirements through internal gain configuration

Applications

• Home Audio systems
