TPA0232PWPR

Overview

The TPA0232PWPR is a stereo Class-AB audio power amplifier in a 24-pin PowerPAD TSSOP package. It delivers 2.8 W per channel into 3-ohm loads with less than 0.4% THD+N at 1 W output. The device operates on a single supply voltage ranging from 4.5 V to 5.5 V, consuming 10 mA during normal operation and 150 µA in shutdown mode. It features integrated DC volume control, input multiplexing, depop circuitry, and PC-beep detection.

Feature Summary

• Integrated DC volume control providing 31 discrete gain steps from +20 dB to -40 dB via the VOLUME terminal.
• Dual stereo input multiplexer selectable via HP/LINE pin for switching between headphone and line inputs.
• Built-in depop circuitry eliminates speaker transients during power-up and shutdown sequences.
• Thermally enhanced PowerPAD package enables high power dissipation in a low-profile surface-mount form factor.

Applications

• Notebook computer internal speakers
• Portable audio devices
• Desktop PC line-out stages

Procurement Notes

Verify component authenticity through authorized Texas Instruments distributors or certified partners. Confirm the presence of the 'R' suffix indicates the taped and reeled variant of the PWP package. Ensure storage conditions respect moisture sensitivity levels to prevent damage prior to soldering.

Selection Notes

Select this component for designs requiring differential inputs and integrated volume management without external resistors. The PowerPAD package is suitable for applications needing thermal performance comparable to larger packages while maintaining a low profile. Verify load impedance requirements align with the specified 3-ohm or 8-ohm configurations.

Part Context

This part belongs to the TPA0232 family of stereo audio amplifiers. It is designed as a direct replacement for legacy solutions requiring integrated gain control and multiplexing. The PWPR suffix denotes the specific tape-and-reel packaging configuration for automated assembly processes.

Replacement Considerations

Check pin compatibility and thermal characteristics when substituting. The standard TPA0232PWP is the non-reel version of this component.
