Product details

Class D mono amp for portable gear — what you need to know

The TPA2025D1YZGT is a single-channel Class D audio amplifier from Texas Instruments, delivering 2.28 W into a 4 Ω load from a 2.5 V to 5.2 V supply. That output is enough for a small speaker in a Bluetooth speaker, a portable radio, or a battery-powered alarm — not a PA system, but plenty for a personal device. The differential inputs help reject ground noise when the amp is fed from a codec or a headphone jack on a long trace. It comes in a 12-DSBGA package, surface-mount only.

Protection features that matter in the field

Short-circuit and thermal protection are built in. If a speaker wire gets pinched or the amp is driven into a dead short, the output stage shuts down instead of letting the magic smoke out. Thermal protection means it can survive a stalled fan or a hot enclosure — useful when the amp is buried inside a sealed product with no airflow.

Frequently asked questions

What is the output power of TPA2025D1YZGT into 4 ohms?

2.28 W into a 4 Ω load, mono channel.

Is TPA2025D1YZGT lead-free and RoHS compliant?

Yes, it is ROHS3 compliant.

What is the pinout of TPA2025D1YZGT?

The pinout is defined in the TI datasheet for the 12-DSBGA package. The bumps are arranged in a 3×4 grid; the datasheet shows the function of each bump.

Is TPA2025D1YZGT a direct substitute for TPA2025D1?

The TPA2025D1 is the base part number; the YZGT suffix indicates the 12-DSBGA package and Tape & Reel packaging. Electrically they are the same die, so the YZGT variant is a drop-in substitute if the board footprint matches the DSBGA land pattern.
