LT6231 8-dip

[Mark-VA]

Okay, I've been searching for the LT6231 8-dip and I don't believe Analog actually make this amp in 8-dip
So that being said what would be the closest amp to this in 8-dip?
Where do you guys buy the most components from?
Digi-Key
Mouser
etc.

Hi Mark-VA,

Now days, integral circuits in DIP-8 case are too old and expensive. Only good solution for using of the new IC's is to use SMD to DIP adapters. One variant for LT6231 is "LCQT-SOIC8-8" type adapter from Farnell ( uk.farnell.com). The Farnell number is 2476033.

Thanks, that is good option if I can't find a comparable amp that is close to the specs of the LT6231

what is your application ?
MCP6022, LT1028

I recommend you try LT6234. If you find it in good quality. In my experience, this is the best of the Dual Amplifier. The case format/type is not a problem.

MCP6022 - Vs (2.5-5.5)V, GBW 10MHz, SR 7V/us, Noise 2.9uVpp at (0.1-10)Hz
LT1028 - Vs (8-44)V, GBW 50MHz, SR 11V/us, Noise 35nVpp at (0.1-10Hz
LT6231 - Vs 3-12V, GBW 200MHz, SR 60V/us, Noise 180nVpp at (0.1-10)Hz
MCP6022 and LT1028 are too slow for first stage of PI MD
MCP6022 is too noisy for first stage of PI MD

For starters you can wind your own coil, its resistance and R set the gain of the circuit. Start with R=100.

The opamp needs at least several MHz of GBW product. You might be able to get away with a TL071. The opamp needs bipolar power (say, +/- 5V). "

Hi Mark-VA,
Part of what scheme is this?

It's a current probe for my scope, or a substitute.
