TPA2031D1 gain and phase, LOT and REEL variations

Other Parts Discussed in Thread: TPA2031D1

In an application utilizing phase delay of audio, what would the production variations be for GAIN and PHASE of the TPA2031D1? 

I expect Gain to probably be 6 sigma centered on the typical, but there is no mention of phase in the internal amp.

On a production reel, could there be more than one LOT?
On a LOT basis, would the gain and phase be fairly well matched?

Your comments please.

    Hi, Ed,

    The gain is spec'd in the d/s. As you mentioned, this will be a distribution about the mean value.

    We didn't measure phase delay on this device.

    I believe one reel could contain two different wafer lots, but I'm not exactly sure how that works. Maybe their is a partial reel at the end of the job.

    There should be better correlation within a lot, but there will be some variation, due to location on the wafer itself as well.
