I am using the ADA4084-1 in a non-inverting, follower configuration in a data acquisition application. The input is AC coupled. At high input power levels, the input suddenly latches to a high value, and will stay there until the input RMS…
OP07 doesn't work on 5V. Use ADA4084-1.
Thank you so much Harry! I'll try ADA4084-1.
Just change to an ADA4084-1, ADA4610-1, or AD8671 and the power dissipation will
be a lot less.
I'm trying to use ADA4084 spice model inside of LTSpice. However, I'm getting errors "Singular matrix: check node u7:82 Iteration No.1", where u7 is one of the ADA4084 instances.
I have read elsewhere online that LTSpice doesn…
I probably posted a message in the wrong forum. Please find below the question related to ADA4084
Datasheet Table 3 specifies that at +/-5V, typical input impedance is [100KOhms||1.1pF]Differential and [200MOhms||2.5pF]Common mode.
ADA4084-1 is next generation OP184; higher speed, less power, less money.

What is your sensor/source impedance?
Yes, on +/-5V, the spec table only guarantees the Input Voltage Range (IVR) to be -2V to +3V
so you are doing better than expected. The ADA4084-1 is RR I/O.
What temp range for the system?
A lot of people have successfully used the 8237, so next time, post a question and let's figure out
why it's not working for you. For a good general purpose op amp that's RR I/O, I would use
the ADA4084-1. (or ADA4528-1, AD8615, etc…
