TDA7269

Overview

The TDA7269 is a class AB dual audio power amplifier in the Multiwatt11 package. It delivers 10W + 10W output at THD=10%, RL=8Ω, and VS=+14V. The supply voltage range is ±5V to ±20V. Key electrical parameters include a quiescent current of 60mA typical, input offset voltage of ±25mV, and total harmonic distortion of 0.03% at 1kHz. Thermal shutdown activates at 145°C.

Feature Summary

• Integrated mute function for pop-free operation
• Stand-by feature with low quiescent current
• Thermal overload protection
• Short circuit protection to ground

Applications

• Hi-Fi music centers
• Stereo TV sets

Procurement Notes
