TDA2052V

Overview

The TDA2052V is a monolithic integrated circuit designed as an audio class AB amplifier in the Heptawatt V package. It operates on split supplies ranging from ±6V to ±25V. The device delivers up to 60W music power into 4Ω loads and 35W continuous RMS output at 10% THD. Key electrical parameters include a quiescent current of 40mA, input offset voltage of 15mV, and open-loop gain of 80dB. It features AC short-circuit protection, thermal shutdown at 145°C, and ESD protection.

Feature Summary

• Integrated mute and stand-by function for remote operation control
• AC short-circuit protection with automatic recovery logic
• Thermal shutdown mechanism preventing overheating damage
• High output current capability supporting low impedance loads

Applications

• Hi-Fi audio power amplification systems
• Television internal audio amplifiers
• Multi-way speaker system subwoofer drivers
• Midrange and tweeter channel amplification

Procurement Notes

Verify the specific suffix 'V' corresponds to the Heptawatt V package variant rather than the Heptawatt H version. Confirm datasheet revision status as specifications are subject to change without notice. Ensure component authenticity through authorized STMicroelectronics distribution channels to guarantee performance reliability.

Selection Notes

Select this component for applications requiring high power output with minimal external components. The wide supply voltage range accommodates various power regulation standards. Consider the Heptawatt V package dimensions for PCB layout constraints. Evaluate thermal management requirements based on ambient temperature and heatsink resistance to maintain safe operating junction temperatures.

Part Context

The TDA2052 belongs to STMicroelectronics' dedicated audio power amplifier family. It serves as a high-performance solution for consumer electronics requiring robust audio output. The device integrates advanced protection circuits typically found in discrete designs, simplifying the overall system architecture while maintaining high fidelity sound reproduction standards.

Replacement Considerations

TDA2052H is the pin-compatible alternative utilizing the Heptawatt H package. Verify mechanical footprint compatibility before substitution. Both variants share identical electrical characteristics and functionality.

FAQ

How does the Mute/Stand-by function operate?

Pin 3 controls the amplifier state via three thresholds. Below 1V it enters Stand-by; between 1.8V and 2.7V it is Muted; above 2.7V it operates in Play mode.

What happens during an AC short-circuit condition?

The amplifier detects the fault and switches to Stand-by mode, limiting DC current flow to the loudspeaker. It automatically resets once the short is removed and output voltage stabilizes within specified limits.
