I have some TLC272s (TI) and TS272s (ST Micro). At first I thought they
were just two manufacturer's name for basically the same part, but then
I had a closer look at the datasheets, and found that the bandwidth
differs. The TS272 gives the gain-bandwidth product as 3.5 MHz, and the
TLC272 gives the unity-gain bandwidth as 1.7 MHz (temperature
dependent).

Does this mean that there is actually a difference in the parts, or that
they were characterized in a different configuration, or that the
unity-gain bandwidth is NOT the same as the gain-bandwidth product at
some lower frequency, or what?
