Of course there is LTC6090 which is unity gain stable. You must be talking about LTC6090-5 which is gain > 5V/V stable only?
For LTC6090-5, if used as an integrator, the circuit could be unstable. That's because when the capacitor acts…
That would not be an issue with LTC6090 being run with +40V and -100V supplies, as shown below in LTspice simulation below:
Here is the LTspice simulation file:

Hi,This is a duplicate thread, continue discussing here LTC6090 LT1006 LTC2057.Regards,Goz
Presently we use the ADA4700 in a system whereby we can produce a very low current draw voltage (between +40 and -40V). The ADA4700 is driven by a DAC to control the output. When selecting the ADA4700, I took note that "rail to rail" is actually +- 2v…
I have used these component to design a sinusoidal current generator 0-2Arms 50Hz-2kHz.
I need to have a very low offset (DC component), max 300-400uA.
Could you please give me help to low the offset?
I'm using the circuit shown on page 18 "Gain of 20 Amplifier with a 40 mA Protected Output Drive" in the datasheet of the LTC6090. The only thing that I have changed, is that I've replaced the 2k resistors with 4k02 to get an amplification of…
As far as I know, the LTspice model for LTC6090 cannot be converted to a Pspice model. And I don't think there are any plans to generate a Pspice model for this device either.
I'm thinking you may be seeing some oscillations that could account for the high supply current you're measuring?
At 35mA supply current (about 2W power with 62V supply) the LTC6090 must be running quite hot / high-temperature to the…
