The INA110 works well for what we need it to do. I am just looking for something that has less noise, or faster, or both. I looked at the INA111, that definitely seems to be a good possibility. The fixed gains of the other amp amp won't cut it though. The sets gains of the INA110 is a good...

Actually I said quite the opposite. I am looking for a better instrumentation amplifier. Price isn't really relevant. I don't care if the chip cost $50 each. As long as its quick, and extremely low noise. With the INA110 right now, the engineers from 88' developed a circuit board that on...

I'm currently looking up digital pot's with dual outputs that are non-serial interface controlled. The DAC's seem like they may be a little more than I need. donpacino - any idea of a circuit to give me a better idea of what to look for? Any specific amp? Actually, while we are on the topic...

Bipolar current output, deferentially haven't tried that search phrase yet. I'll check it out.

Thanks for the quick reply. In theory, I understand how they work, but I have never used them in practice. Any examples of one that I could look into, maybe give you a better idea of what aspects that I like/dislike about it and why it may or may not work? I looked over a couple on digikey...

Hello, I was looking for some sort of chip/IC that would accept a digital input of say 4-5 bits and that would adjust an output current. I am looking to have a +/-3.3mA current applied to a resistive load. It would also be helpfull (for testing purposes) if I could adjust the inputs so that I...
