Is TAS2553 TI's lowest power smart amp?

I need a smart amp with I2S input lines but only need to hit a range of 0.25-0.5W or so.

Hi AD,

Yes, the TAS2553 is the lowest power amplifier from the low-power digital input amplifiers (TAS25xx).
TAS2553 features I/V sense but the data processing should be performed by an external processor; TAS2555, TAS2557 and TAS2559 have dedicated processing.

Hi Ivan, Did you mean to say TAS2552 has dedicated processing? As opposed to TAS255?

AD,

I meant TAS2555, sorry for the typo.
I've just corrected my last reply.
TAS2552 is similar to TAS2553, it features I/V sense but the data processing should be performed by an external processor.
