TPA2025D1YZGR

Overview

The TPA2025D1YZGR is a single-channel Class-D audio amplifier manufactured by Texas Instruments. It delivers an output power of 1.7 W into a 4-ohm load with a total harmonic distortion plus noise of 0.15%. The device operates on a supply voltage ranging from 2.3 V to 5.2 V and features a fixed gain of 20 dB. It draws a working supply current of 1.8 A and functions within a temperature range of -40°C to +85°C. The component is housed in a compact 12-DSBGA package designed for surface-mount installation.

Feature Summary

• Class-D topology providing high efficiency for battery-powered applications
• Integrated differential input stage for improved noise immunity
• Built-in thermal and short-circuit protection mechanisms

Applications

• Portable media players
• Mobile phones
• Personal digital assistants

Procurement Notes

Verify the suffix 'YZGR' corresponds to the tape-and-reel packaging variant rather than cut-tape or other formats. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the ordering part number matches the specific reel quantity requirements for your production line.

Selection Notes

Select this component when a mono audio solution is required with minimal external filtering. The fixed 20 dB gain simplifies circuit design compared to adjustable gain variants. Consider the 12-DSBGA package size constraints against available PCB real estate for optimal thermal performance.

Part Context

This part belongs to the TPA2025D1 series, which focuses on low-power audio amplification. It serves as a complement to higher-power models like the TPA2028D1 or stereo options within the broader Texas Instruments audio portfolio. The DSBGA footprint distinguishes it from larger SOIC or QFN packages found in other series members.

Replacement Considerations

The TPA2025D1YZGT is a compatible alternative differing primarily in packaging format (cut tape vs. reel). Verify pinout compatibility and electrical specifications before substitution.
