TPA032D01DCARG4

Overview

The TPA032D01DCARG4 is a monolithic Class-D mono audio power amplifier by Texas Instruments. It delivers up to 10 W of continuous average power into a 4-ohm load at 0.5% THD+N from a 12-V supply. The device operates with supply voltages ranging from 8 V to 14 V and features a bridge-tied load (BTL) configuration that eliminates external output coupling capacitors. It utilizes a thermally enhanced 48-pin PowerPAD TSSOP surface-mount package.

Feature Summary

• Bridge-tied load (BTL) architecture for high-efficiency single-channel operation without output coupling capacitors
• Integrated thermal and under-voltage protection with status feedback terminals for fault monitoring
• Low shutdown current consumption suitable for battery-powered applications
• High switching frequency enabling the use of small passive output filter components

Applications

• Battery-powered audio systems requiring low standby current
• Mono speaker drivers in consumer electronics
• High-fidelity audio frequency range reproduction (20 Hz to 20 kHz)

Procurement Notes

Verify the 'R4' suffix indicates tape and reel packaging, as standard DCA variants may be available in tubes. Confirm RoHS compliance status for the specific revision. Ensure the component matches the 48-pin PowerPAD TSSOP physical dimensions. Check for obsolescence or lifecycle changes prior to final design approval.

Selection Notes

Select this component for designs requiring a single-channel Class-D solution with integrated protection. The BTL topology simplifies board layout by removing large output capacitors. Verify that the application can accommodate the required 48-pin package size and thermal dissipation requirements on the PCB.

Part Context

This part belongs to the TPA032D01 family of extremely efficient Class-D mono amplifiers. The base model TPA032D01 is offered in a 48-pin PowerPAD TSSOP package. The device is designed for 12-V operation but supports a wider voltage range of 8 V to 14 V.

Replacement Considerations

TPA032D01DCA is the tube-packaged equivalent of this component. Both share identical electrical specifications and pinouts; the selection depends solely on the required packaging format.
