TDA7266 (7+7W) Dual Bridge Amplifier

TDA7266 (7+7W) Dual Bridge Amplifier

The TDA7266 is a dual-channel bridge amplifier in a compact Multiwatt‑15 package, delivering 7 W per channel into 8 Ω at 10% distortion designed for audio applications such as televisions and portable radios. Operating on a single power supply ranging from 3 V up to 18 V, the device requires minimal external components thanks to its internal fixed gain structure and lack of bootstrap or Boucherot components. Integrated standby and mute pins let designers control output activation to prevent power-on transients.

The amplifier includes comprehensive thermal and short-circuit protection circuits to enhance safety and reliability. It maintains quiescent current around 50–65 mA, with internal biasing ensuring stable performance. Dual ground pins help reduce noise and ground-loop issues, while the package supports up to 2 A peak current and 33 W total dissipation under a 70 °C case condition.

With operating temperatures from –10 °C to +70 °C (storage up to +150 °C), it provides durable, space-efficient stereo amplification with robust protection aimed at compact, battery-powered or low-voltage audio systems.

Features:

• Wide supply range: 3 V to 18 V.
