AD8515 vs TLV9064

[bitrex]

can anyone spot the reason to use the single AD8515 low-voltage RRIO amp
over the quad TLV9064? In most areas it looks like the TLV9064 has
superior performance to the AD part and you get four for about the same
price...

Didn't look at spec sheets, but space. You only have room for a single opamp.
(and only need one.)

Uh huh, there's that.

I thought sure there must be an advantage to buying a hoity-toity AD
part, ooh we're fancy we bought another fancypants botique chip-company
LTC, as opposed to the Burger King of the component industry, texas
instruments, but a cursory examination of the spec sheet I can't seem to
see it

At a glance without studying deeply I'd prefer the TI part: it mentions
RFI/EMI filtering; is slightly quieter; has beefier output. The AD part
doesn't say it can be used for E-Bikes! (Honestly why do manfrs write
such silly application suggestions?)

Both parts are available in SOT-23 and SC70. The TI part is available in SOT553 and X2SON as well(leadless).

Because they know their markets! Those are the sort of comments that can be the difference in the part showing up in a search and not. If they don't know your part exists, they can't buy them...

I'm just sayin'
