Overview
The TPA0233DGQR is a mono Class-AB audio power amplifier with integrated headphone drive, manufactured by Texas Instruments. It delivers 2 W of output power into a 4-Ω load and operates from a single supply voltage ranging from 2.7 V to 5.5 V. The device features a 10-pin HVSSOP package with an exposed pad for thermal management. It includes built-in soft-start circuitry to minimize turn-on pop noise and offers enable/shutdown functionality for power control.
Feature Summary
- Integrated headphone driver capability for direct connection to high-impedance loads
- Built-in soft-start mechanism to reduce audible switching transients during power-up
- Enable and shutdown pin configuration for system-level power management
Applications
- Portable media players and MP3 devices
- Mobile phones and smartphones
- Personal digital assistants (PDAs)
- Handheld gaming consoles
Procurement Notes
Verify the exact suffix 'DGQR' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the 10-pin HVSSOP footprint matches your PCB design, specifically noting the exposed thermal pad requirements for adequate heat dissipation. Ensure component authenticity through authorized distributors to avoid counterfeit risks associated with TI ICs.
Selection Notes
Select this component when a compact mono amplifier solution is needed for battery-powered portable electronics. It is suitable for applications requiring both speaker and headphone outputs without additional buffering stages. Consider the 2-W power rating against the specific impedance of the connected load to ensure sufficient volume levels. Evaluate the single-supply operation compatibility with the system's available voltage rails.
Part Context
The TPA0233 belongs to Texas Instruments' TPA02xx series of audio amplifiers designed for low-voltage consumer applications. This series focuses on providing high-quality audio performance in minimal space. The DGQR variant specifically denotes the surface-mount HVSSOP package with reel packaging, distinguishing it from leaded or cut-tape versions within the same functional family.
Replacement Considerations
Direct substitutes include TPA0233DGQ (cut-tape version) and other members of the TPA02xx series such as TPA0213 or TPA0223, provided pinout and power requirements align. Verify package compatibility and thermal characteristics when swapping between variants.
