TPA2008D2PWPR

Overview

The TPA2008D2PWPR is a stereo Class-D audio amplifier manufactured by Texas Instruments, housed in a 24-HTSSOP package. It operates on a single supply voltage ranging from 4.5 V to 5.5 V. The device delivers up to 3 W of continuous output power per channel into a 3-ohm load. Key electrical specifications include a shutdown feature for power management and an operating temperature range spanning from -40°C to +85°C.

Feature Summary

• Integrated volume control functionality allowing direct adjustment without external digital interfaces
• Built-in pop-and-click suppression circuitry to minimize audible transients during power-up and power-down sequences
• Comprehensive protection mechanisms including thermal shutdown and short-circuit protection to ensure operational reliability

Applications

• Portable media players requiring low-voltage stereo audio amplification
• Mobile phones and smartphones with integrated speaker outputs
• Personal navigation devices (PNDs) utilizing compact form-factor audio stages
• MP3 players and digital audio recorders

Procurement Notes

Verify the specific suffix PWPR corresponds to the 24-HTSSOP surface-mount package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the input voltage range aligns with your system's 4.5 V to 5.5 V supply rails before integration.

Selection Notes

Select this component when a dual-channel stereo solution is required within a strict 5.5 V maximum supply constraint. It is suitable for applications prioritizing volume control integration and pop-suppression over high-power output. Consider alternative models if operation above 5.5 V or mono-only configurations are needed.

Part Context

This part belongs to the TPA2008 series of low-voltage Class-D audio amplifiers. It is designed for battery-powered consumer electronics where efficiency and small footprint are critical. The series typically offers integrated features like volume control and protection, distinguishing it from basic amplifier ICs that require extensive external components.

FAQ
