Overview
The HPA00169DGNR is a mono, fully differential Class-AB audio power amplifier manufactured by Texas Instruments. It delivers 3.1 W of output power into a 3-ohm load. The device operates within an ambient temperature range of -40°C to +85°C and utilizes an 8-pin HVSSOP package. Designed for analog input applications, it integrates precision load switch capabilities within the HPA series architecture.
Feature Summary
- Fully differential output topology for improved noise rejection
- Compact Class-AB design optimized for space-constrained systems
- Integrated precision load switch functionality
Applications
- Portable audio devices requiring mono amplification
- Embedded audio systems with limited board space
- Battery-powered consumer electronics
Procurement Notes
Verify the exact datasheet version and revision history before integration, as component specifications may vary between manufacturing lots. Confirm that the 8-HVSSOP footprint matches your PCB layout constraints. Ensure thermal management strategies align with the -40°C to +85°C operating range specified in the official documentation. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a single-channel, high-efficiency audio solution is required for low-voltage applications. The fully differential architecture makes it suitable for environments where common-mode noise interference is a concern. Consider the 3-ohm load capability when designing speaker interfaces. Evaluate the thermal performance characteristics against your system's power dissipation limits to ensure reliable operation under continuous use conditions.
Part Context
This part belongs to the HPA series from Texas Instruments, which focuses on compact audio amplification solutions. The series emphasizes efficiency and small form factors for modern portable electronics. The HPA00169DGNR specifically targets mono audio applications where space savings and adequate power delivery are critical design parameters.
Replacement Considerations
Consult official Texas Instruments substitution guides for verified alternatives. No public substitute part numbers are confirmed in available documentation.
