Product details

Class D/G mono amplifier for portable and industrial audio

At low signal levels it runs in Class G for better efficiency; at higher output it transitions to Class D to deliver the full 4W into an 8Ω load without a large heatsink. Short-circuit and thermal protection are included on-die, so the amp survives a miswired speaker terminal or a stalled fan in an outdoor telecom enclosure.

The 4W rating into 8Ω is the maximum continuous output per channel before clipping.

TI lists the TAS2552YFFT as Active. That means standard factory lead times through distribution, no last-time-buy clock running, and full datasheet support. The ROHS3 compliance covers the current EU exemption list.

The 30-DSBGA is a wafer-level package with solder balls on the bottom. Reflow profile follows standard JEDEC for lead-free solders.

Frequently asked questions

What is the output power of TAS2552YFFT at 8 ohm?

The TAS2552YFFT delivers 4W into an 8Ω load from a single channel (mono output).

Does TAS2552YFFT have short-circuit protection?

Yes, the TAS2552YFFT includes on-die short-circuit and thermal protection.

Is TAS2552YFFT a replacement for TAS2552?

The TAS2552YFFT and TAS2552 share the same amplifier core but differ in package — the YFFT suffix indicates the 30-DSBGA wafer-level package. If your layout expects a different package (e.g., QFN), the TAS2552 in that package is the functional equivalent; verify footprint compatibility before substituting.
