TPA0252PWP

Overview

The TPA0252PWP is a stereo audio power amplifier manufactured by Texas Instruments, housed in a 24-pin HTSSOP package. It delivers 2 W per channel into a 3-ohm load at 5 V in bridge-tied load (BTL) configuration. The device operates within a supply voltage range of 4.5 V to 5.5 V and features internal depop circuitry to minimize output transients during power-up. It supports digital volume control ranging from 20 dB to -40 dB with memory retention for settings after shutdown.

Feature Summary

• Integrated digital volume control with memory retention for persistent settings across power cycles
• Internal depop circuitry designed to minimize audible transients during power-up sequences
• Flexible input architecture supporting differential stereo inputs and dedicated PC beep functionality
• Configurable output modes allowing selection between bridge-tied load (BTL) and single-ended operation

Applications

• Portable multimedia devices requiring integrated volume management
• Computer peripheral audio systems utilizing PC beep inputs
• Battery-powered consumer electronics operating on regulated 5 V supplies
• Automotive infotainment sub-systems compatible with standard automotive voltage regulation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct pinout and thermal specifications. Confirm RoHS compliance status as manufacturing processes may evolve. Cross-reference the datasheet revision date with your design timeline to account for any potential parameter updates or lifecycle changes before finalizing procurement orders.

Selection Notes

Select this component when a compact stereo amplifier with built-in digital volume control is required. Ensure the application utilizes a stable 5 V supply rail, as the device is optimized for this voltage range. Verify that the load impedance meets the minimum 3-ohm requirement for BTL configurations to maintain specified performance levels and prevent thermal overload.

Part Context

This part belongs to Texas Instruments' legacy audio amplifier portfolio, specifically designed for low-voltage stereo applications. It integrates power amplification with control logic, reducing external component count compared to discrete solutions. The HTSSOP package facilitates surface-mount assembly in space-constrained portable electronic designs.
