TDA7266P

Overview

The TDA7266P is a dual-channel Class-AB audio power amplifier manufactured by STMicroelectronics. It delivers 6W of output power into an 8-ohm load and operates on a single supply voltage ranging from 3.5V to 12V. The device features a fixed internal gain of 26dB, a maximum quiescent current of 2A, and a total harmonic distortion plus noise of 0.05%. It utilizes a PowerSSO-24 surface-mount package with dimensions of 7.6mm width and supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Dual bridge amplifier architecture designed for stereo audio applications
• Integrated thermal overload and short-circuit protection mechanisms
• Supports standby and mute functions for power management
• Requires minimal external components due to internally fixed gain

Applications

• LCD TV and monitor audio systems
• PC motherboard integrated audio solutions
• Portable radio and audio devices

Procurement Notes

Verify the specific suffix 'P' indicates the PowerSSO-24 surface-mount package variant distinct from through-hole or other package types within the family. Confirm RoHS compliance status and REACH SVHC declarations against the latest manufacturer documentation before integration. Ensure the selected component matches the required 24-pin configuration and lead-free specifications for the target assembly process.

Selection Notes

Select this component when a compact surface-mount solution is required for low-to-mid power stereo amplification. The 3.5V to 12V supply range suits battery-operated or low-voltage DC-powered consumer electronics. Consider the 26dB fixed gain and 0.05% THD+N for standard fidelity requirements where external gain setting networks are undesirable.

Part Context

The TDA7266P belongs to the TDA7266 series of dual bridge audio amplifiers. This series includes various package options such as Multiwatt-15 (through-hole) and PowerSO-20 (surface-mount). The P suffix specifically denotes the PowerSSO-24 package, differentiating it from other physical form factors while maintaining similar core electrical characteristics within the product line.

Replacement Considerations

Cross-reference with TDA7266D for alternative surface-mount configurations. Verify pinout compatibility and thermal dissipation requirements when substituting between different package types within the same amplifier family.
