Overview
The NAU82039VG TR is a Class D audio amplifier manufactured by Nuvoton Technology Corporation. It features a single-channel (mono) output configuration housed in a 9-WLCSP package with dimensions of 1.21 x 1.22 mm. The device operates within a supply voltage range of 2.5V to 5.5V and supports an operating temperature range of -40°C to 85°C. It delivers a maximum output power of 3.2W into a 4-ohm load. Key integrated features include pop-and-click elimination and thermal protection mechanisms.
Feature Summary
- Class D amplification topology for efficient audio signal processing
- Integrated pop-and-click elimination circuitry
- Built-in thermal protection for operational safety
Applications
- Portable consumer electronics requiring mono audio output
- Battery-powered devices utilizing low-voltage operation
- Compact audio modules constrained by small form factor requirements
Procurement Notes
Verify component status prior to procurement as the NAU82039VG TR is listed as obsolete and no longer manufactured. Confirm availability through authorized distributors or check for direct replacement options such as the NAU82011VG. Ensure that the 9-WLCSP package compatibility matches the target PCB design constraints before finalizing sourcing decisions.
Selection Notes
Select this component for applications requiring a compact, single-channel Class D amplifier with integrated protection features. Consider the 9-WLCSP package size for space-constrained designs. Evaluate the 2.5V to 5.5V supply range against system power rails. Verify that the 3.2W output capability at 4 ohms meets the specific acoustic requirements of the target application.
Part Context
This component belongs to the Nuvoton audio amplifier product line, specifically designed for high-efficiency sound reproduction in portable devices. The WLCSP packaging allows for minimal footprint usage compared to traditional packages. As part of the manufacturer's portfolio, it targets markets demanding reliable audio performance within strict physical and electrical constraints.
Replacement Considerations
The NAU82011VG is identified as a direct substitute for the NAU82039VG TR. Verify pinout compatibility and functional equivalence before implementation. Check current manufacturing status and availability for both parts.
