Procurement Notes

Verify the specific ordering suffix YCGR against the official TI Package Option Addendum to confirm the DSBGA-36 carrier type and 3000-unit large tape-and-reel quantity. Ensure that the required supply voltages (VBAT, VDD, IOVDD) align with the datasheet specifications before finalizing procurement orders.

Selection Notes

Select this component when high audio fidelity and extended battery life are critical for portable devices. The integrated boost eliminates external inductor requirements, while the IV-sense capability allows for precise speaker protection without additional sensing hardware. Verify compatibility with the host processor's digital audio interface protocols.

Part Context

The TAS2572 belongs to Texas Instruments' smart amplifier family designed for mobile and wearable electronics. It combines a Class-D amplifier with a high-voltage boost converter to maximize output power from single-cell or multi-cell lithium-ion batteries. The device targets applications requiring high sound pressure levels while maintaining strict power consumption constraints.

Replacement Considerations

Consult the official Texas Instruments product selection guide for verified cross-reference part numbers. Do not substitute based on generic specifications; ensure functional equivalence regarding the integrated boost architecture and digital interface compatibility.

FAQ

Does the TAS2572 require an external master clock?

No, the device supports MCLK-free operation and features auto clock rate detection for I2S/TDM inputs ranging from 16 kHz to 192 kHz.

How does the TAS2572 protect the connected loudspeaker?
