Overview
The TPA0312PWPRG4 is a stereo audio power amplifier manufactured by Texas Instruments, housed in a 24-HTSSOP package. It delivers 2.6 W of continuous output power per channel into an 8-ohm load with a 5-V supply and less than 0.1% THD+N. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports an operating temperature from -40°C to +85°C. Key electrical specifications include a quiescent current of 12 mA and a shutdown current of 0.5 µA.
Feature Summary
- Four selectable gain settings allow flexible integration with various source devices.
- Multiplexer (MUX) control enables dynamic switching between gain configurations.
- Integrated soft-start circuitry minimizes turn-on pop noise during power-up.
- Thermal shutdown protection safeguards the device against overheating.
Applications
- Portable media players
- Mobile phones
- Personal digital assistants
Procurement Notes
Verify the component authenticity by checking the manufacturer's part marking against official datasheet standards. Confirm the presence of the 'G4' suffix indicates lead-free and RoHS compliance. Ensure the 24-HTSSOP package dimensions match your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this amplifier for low-voltage stereo audio applications requiring minimal external components. The four-gain configuration provides design flexibility for different input signal levels. Consider the thermal performance in enclosed designs due to the compact HTSSOP package.
Part Context
This component belongs to the TPA0312 family of stereo audio amplifiers designed for portable electronics. It offers a balance of high efficiency and low distortion in a small form factor, suitable for battery-powered devices where space and power consumption are critical constraints.
Replacement Considerations
The TPA0312PWP is a non-RoHS compliant variant of the same functional device. Verify that environmental compliance requirements align with the G4 suffix designation when substituting.
