TDA7262

Overview

The TDA7262 is a Class AB dual Hi-Fi audio power amplifier designed for high-quality stereo applications. It delivers up to 28W music power per channel at 4Ω with a 32V supply, or 20W continuous power at THD=10%. The device operates on a wide supply voltage range of 8V to 32V and supports peak output currents up to 3.5A. It features a built-in stand-by function with significant attenuation, AC short-circuit protection, and thermal shutdown at 145°C. The amplifier utilizes a Multiwatt11 package.

Feature Summary

• Dual bridge architecture providing high current capability for stereo applications
• Integrated stand-by mode offering deep signal attenuation and low quiescent current
• Built-in protection systems including thermal overload and AC short-circuit safeguards

Applications

• Hi-Fi music centers
• Television sets
• High-quality stereo audio equipment

Procurement Notes

Verify component status before procurement as the TDA7262 is listed as an obsolete product by STMicroelectronics. Confirm availability through authorized distributors or secondary market suppliers. Ensure that any replacement components maintain compatible pinouts, thermal characteristics, and electrical specifications to ensure seamless integration into existing designs without requiring circuit modifications.

Selection Notes

Select this component for designs requiring robust Class AB amplification with integrated protection mechanisms. The wide supply voltage tolerance allows flexibility in power supply design. Consider the Multiwatt11 package dimensions and thermal resistance requirements when designing the heatsinking solution. Verify that the required closed-loop gain settings align with the external resistor values specified in the application circuit guidelines.

Part Context

The TDA7262 belongs to STMicroelectronics' legacy audio amplifier portfolio, specifically engineered for consumer electronics requiring reliable stereo sound reproduction. It is part of a series that includes variants like the TDA7263 and TDA7266, which offer different power outputs and packaging options. This specific model targets the mid-to-high-end segment of traditional audio hardware markets.
