New big boy op amp...

[bitrex]

Not as high a max supply voltage as the TCA0372, but that\'s a big boy
slew rate and output current for the price:

Hmm, the data sheet says 2013, have they just been hiding at Digi Key
all this time?

If it needs an amp,the display must be very big.

I hope the thermal limit actually works. It doesn\'t on TCA0372.

Potentially nice part. It’s about 12 MHz GBW, vs 1.4ish for the TCA0372 or
the old Fairchild L272, or a pitiful 350 kHz for the ST version.

It has a power pad, and costs 67 cents in hundreds. (The others have gone
way up in price.)

LCSC doesn’t have any, which is a bit inconvenient.

It’s only marginally stable at unity gain—like 10 dB peaking, and the
datasheet isn’t exactly PMI quality.
