TPA0252PWPG4

Overview

The TPA0252PWPG4 is a stereo 2-W audio power amplifier IC manufactured by Texas Instruments. It features integrated digital volume control ranging from 20 dB to -40 dB and internal memory to restore settings after shutdown. The device supports dual-channel bridge-tied load (BTL) or single-ended operation, delivering 2 W per channel into a 3-ohm load at 5 V. It includes an internal input multiplexer for selecting between line and headphone inputs, a PC beep input, and differential stereo inputs. Internal depop circuitry minimizes output transients during power-up.

Feature Summary

• Integrated digital volume control with internal memory retention
• Internal depop circuitry to minimize output transients
• Dual-channel BTL or single-ended output configuration
• Internal input multiplexer for multiple audio sources

Applications

• Evaluation of stereo audio power amplification circuits
• Integration into portable consumer audio devices
• Development of systems requiring digital volume adjustment
• Testing of bridge-tied load speaker configurations

Procurement Notes

Verify the component datasheet SLOS288 for current electrical specifications and operating conditions. Confirm that the G4 suffix indicates lead-free and RoHS compliance as per Texas Instruments standards. Ensure design safeguards are implemented to protect against overvoltage or reverse polarity, which may damage the platform or module. Validate that all application parameters align with the manufacturer's published limits before finalizing orders.

Selection Notes

Select this component for applications requiring a compact stereo amplifier with built-in digital volume management. The device is suitable for designs needing flexible input routing via its internal multiplexer. Consider the requirement for a regulated 5 V supply and the specific control signal logic levels for shutdown and mode selection. Evaluate the thermal performance requirements based on the intended load impedance and output power configuration.

Part Context

The TPA0252 is part of Texas Instruments' portfolio of mixed-signal audio products designed for consumer electronics. It is often utilized in evaluation modules such as the SLOP333, which facilitate rapid prototyping and testing within the TI plug-n-play audio amplifier evaluation platform ecosystem. This context highlights its role in development workflows rather than end-product integration alone.
