TPA032D01DCA

Overview

The TPA032D01DCA is a monolithic Class-D mono audio amplifier in a 48-pin PowerPAD TSSOP package. It delivers 10 W continuous average power into a 4-ohm load at 0.5% THD+N from a 12-V supply, with a peak music power of 32 W. Operating voltage ranges from 8 V to 14 V. The device features a bridge-tied load configuration eliminating output coupling capacitors, low shutdown current of 20 µA, and thermal/under-voltage protection.

Feature Summary

• Bridge-tied load (BTL) architecture eliminates the need for external output coupling capacitors.
• Integrated chip-level shutdown control significantly reduces total supply current for battery conservation.
• Built-in thermal and under-voltage protection circuitry enhances device reliability during fault conditions.

Applications

• High-fidelity audio frequency range reproduction
• Battery-powered applications requiring low standby current
• Mono speaker driving systems

Procurement Notes

Verify the specific DCA package designation and revision level against the manufacturer's datasheet SLOS282B. Confirm that the application circuit supports the required 12-V operation and thermal dissipation capabilities. Ensure compatibility with the 48-pin PowerPAD TSSOP footprint for surface-mount assembly.

Selection Notes

Select this component for designs requiring high-efficiency Class-D amplification without external output filters. The BTL configuration simplifies board layout by removing large coupling capacitors. Verify that the system can accommodate the thermally enhanced PowerPAD package requirements for adequate heat dissipation.

Part Context

This part belongs to the TPA032 series of extremely efficient Class-D mono audio amplifiers. It utilizes high-speed power DMOS transistors to replicate analog input signals through high-frequency switching. The design focuses on delivering high power output with minimal heat generation compared to linear amplifiers.

Replacement Considerations

TPA032D01DCAR is the tape-and-reel version of the same device. Verify pinout and electrical specifications match before substitution.
