TDA7292

Overview

The TDA7292 is a Class-AB dual audio power amplifier by STMicroelectronics, housed in a Multiwatt-11 package. It delivers 40 W + 40 W into an 8 Ω load with ±26 V supply and 10% THD. Operating on split dual supplies from 8 V to 35 V, it features 80 dB gain, 0.02% THD+N, and 500 nA input bias current. Designed for through-hole mounting, it operates between 0°C and +70°C.

Feature Summary

• Integrated mute function eliminates switching noise during turn-on and turn-off
• Standby mode reduces quiescent current consumption
• Built-in thermal overload protection safeguards against overheating
• Short-circuit protection prevents damage under fault conditions

Applications

• Hi-fi music centers
• Stereo TV sets
• High-quality sound applications

Procurement Notes

Verify the specific ordering suffix to confirm the exact package variant and environmental compliance status. Confirm that the Multiwatt-11 package matches your PCB footprint requirements. Ensure the supply voltage range aligns with your system design before procurement.

Selection Notes

Select this component for stereo applications requiring high output power with low distortion. The wide supply voltage range allows flexibility in power supply design. Consider the through-hole installation method when designing the circuit board layout.
