TPA2025D1YZGT

Overview

The TPA2025D1YZGT is a single-channel Class-D audio amplifier manufactured by Texas Instruments. It features an integrated Class-G boost converter to deliver constant output power of up to 2W into a 4-ohm load. The device operates within a supply voltage range of 2.3V to 5.2V and maintains a total harmonic distortion plus noise (THD+N) of 0.15%. It utilizes a 12-pin DSBGA package, supports a fixed gain of 20 dB, and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates a Class-G boost converter for consistent audio performance
• Provides differential input capability with short-circuit and thermal protection
• Delivers constant output power independent of supply voltage variations

Applications

• Portable media players
• Mobile phones
• Personal digital assistants

Procurement Notes

Verify the specific suffix YZGT to confirm the 12-DSBGA package configuration and reel packaging type. Ensure compatibility with the required 2.3V to 5.2V supply rails and 4-ohm load impedance. Confirm RoHS compliance status and moisture sensitivity level requirements before integration into the final assembly process.

Selection Notes

Select this component when a mono audio solution requires high efficiency and constant power delivery in a minimal footprint. The integrated boost converter eliminates external inductors typically needed for Class-D amplifiers. It is suitable for battery-powered devices where maximizing speaker volume at low supply voltages is critical.

Part Context

This part belongs to the TPA2025D1 series of constant output power Class-D audio amplifiers. It is designed specifically for portable applications requiring high sound quality in a small form factor. The series emphasizes simplicity of design by integrating necessary power management functions directly onto the silicon die.

Replacement Considerations

Direct substitutes include other members of the TPA2025D1 family or similar TI Class-D amplifiers like the TPA2080D1, provided pinout and electrical specifications match the existing design constraints.
