TPA0132PWPR

Overview

The TPA0132PWPR is a stereo audio power amplifier in a 24-pin TSSOP PowerPAD package. It delivers 2.8 W per channel into 3-ohm loads with less than 0.4% THD+N at 1 W into 8-ohm speakers. The device features DC volume control from 20 dB to -40 dB, internal gain control, and depop circuitry. Operating voltage ranges from 4.5 V to 5.5 V. Supply current is 10 mA in normal operation and 150 µA in shutdown mode.

Feature Summary

• Integrated DC volume control providing 31 discrete gain steps
• Internal input multiplexer for switching between line and headphone inputs
• Depop circuitry eliminates speaker transients during power transitions
• PowerPAD thermal enhanced packaging for high heat dissipation

Applications

• PC desktop line-out circuits
• Notebook computer internal speakers
• Portable audio devices driving 8-ohm loads

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration. Confirm the package type corresponds to the thermally enhanced PowerPAD variant. Ensure the supply voltage range aligns with system requirements. Check for moisture sensitivity handling instructions during storage.

Selection Notes

Select this component for designs requiring integrated volume control without external digital interfaces. The PowerPAD package is suitable for applications needing robust thermal performance in compact spaces. Consider the BTL versus SE mode switching capabilities when designing output stages for different load impedances.

Part Context

This part belongs to Texas Instruments' stereo audio power amplifier family. It utilizes a Class-AB output stage architecture. The device is designed to minimize external component count while maintaining high fidelity audio reproduction. It supports both single-ended and bridge-tied load configurations.
