Overview
The TPA0132PWP is a stereo Class-AB audio power amplifier in a 24-pin PowerPAD TSSOP package. It delivers 2.8 W per channel into 3 Ω loads and operates on a single 5 V supply. Key features include integrated DC volume control with 32 discrete steps from +20 dB to -40 dB, an internal input MUX for line or headphone sources, and PC-beep detection. The device incorporates depop circuitry to eliminate startup transients and offers low shutdown current of 150 µA.
Feature Summary
- Integrated 32-step DC voltage-controlled volume adjustment
- Internal multiplexer for switching between line and headphone inputs
- Built-in depop circuitry to prevent speaker popping during power cycles
- PC-beep input capability for system notification signals
Applications
- Notebook computer internal speakers
- Desktop PC line-out stages
- Portable audio devices requiring low-power amplification
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging type, as the base part number may be available in tubes or tape-and-reel formats. Ensure the thermal pad connection requirements are met in the PCB layout design to maintain specified thermal performance and reliability standards.
Selection Notes
Select this component for designs requiring a single-supply stereo amplifier with minimal external components. It is suitable for applications needing integrated gain control and input switching without additional logic. Consider the thermal constraints of the PowerPAD package when designing for high ambient temperatures or continuous full-power operation.
Part Context
This device belongs to Texas Instruments' legacy audio amplifier portfolio, specifically designed for PC99 compliance in desktop and portable computing environments. It represents a solution for integrating audio output stages directly onto mainboards or portable device motherboards where space and component count are critical constraints.
Replacement Considerations
Consult official substitution guides for direct pin-compatible alternatives within the same family. Verify that any replacement maintains the required 24-pin PowerPAD TSSOP footprint and thermal characteristics.
