TPA152DRG4

Overview

The TPA152DRG4 is a stereo Class-AB audio power amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and delivers up to 75mW per channel into a 32-ohm load. The device is housed in an 8-SOIC package with a width of 3.90mm. It supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Integrated pop-and-click suppression circuitry to minimize audible noise during power transitions
• Built-in thermal shutdown and short-circuit protection mechanisms for enhanced operational reliability

Applications

• Portable audio devices requiring low-voltage stereo amplification
• Mobile communication handsets with integrated speaker outputs
• Compact multimedia players utilizing single-supply operation

Procurement Notes

Verify the specific suffix DRG4 against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering information matches the exact package dimensions and moisture sensitivity level required for your assembly process. Cross-reference the component marking code with official identification guides to prevent counterfeit substitution.

Selection Notes

Select this component when a dual-channel solution is required within a constrained 8-pin surface-mount footprint. It is suitable for designs needing Class-AB performance at low supply voltages without external biasing components. Consider the thermal characteristics and maximum output power limits relative to the intended speaker impedance and enclosure size.

Part Context

This part belongs to the TPA152 family of audio amplifiers, designed specifically for portable applications. It serves as a complete stereo amplifier solution, eliminating the need for external coupling capacitors or complex bias networks. The device integrates essential protection features typically found in higher-power industrial amplifiers but scaled for consumer electronics efficiency.
