Overview
The TPA152DR is a stereo Class-AB audio amplifier integrated circuit manufactured by Texas Instruments. It operates on a single supply voltage ranging from 4.5V to 5.5V and is housed in an 8-SOIC package. The device delivers up to 75mW per channel into a 32-ohm load. It features built-in pop-and-click suppression, mute functionality, and protection against short circuits and thermal overload. The component supports surface-mount installation and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrated pop-and-click suppression for noise-free startup and shutdown
- Built-in mute control capability for signal management
- Short-circuit and thermal protection mechanisms for reliability
Applications
- Portable headphone amplification
- Stereo audio output stages
- Low-voltage consumer electronics
Procurement Notes
Verify the specific ordering suffix to ensure the correct tape and reel configuration matches your assembly requirements. Confirm that the RoHS compliance status aligns with your manufacturing standards. Cross-reference the datasheet revision date to ensure compatibility with your design specifications. Ensure the SOIC package dimensions fit your PCB footprint constraints before finalizing procurement.
Selection Notes
Select this component when a low-voltage, dual-channel audio solution is required for portable devices. It is suitable for applications needing Class-AB performance with minimal external components. Consider the 8-SOIC package size for space-constrained designs. Verify that the 4.5V to 5.5V supply range matches your system power architecture.
Part Context
This part belongs to the TPA152 series of audio amplifiers from Texas Instruments. It is designed for stereo applications requiring high efficiency and low distortion in compact packages. The DR suffix indicates the specific tape and reel packaging variant available for automated surface-mount assembly processes.
Replacement Considerations
Check for direct pin-compatible substitutes within the same manufacturer's portfolio. Verify electrical parameters such as supply voltage range and output power capabilities. Ensure the replacement maintains the same package type and thermal characteristics.
