I have built a voltage amplify circuit with OP297GS.
But sometimes, circuit does not work right, and that will not back to normal.
There is an potentiometer before the Input pin (pin2), but I can't adjust output voltage.
So, I exchange that OP297 with new one, then the circuit work right.
I wish you to teach me.
On the datasheet, Output Voltage Swing Condition is RL=2kΩ to RL=10kΩ.
Can I use OP297 out of these conditions?
On the data sheet, AC performance is written as below.
"the OP297 displays excellent responce with 1000 pF loads."
Can I use bigger capacitance than 1000pF?
I'm afraid these thing is the key of my problem.(or the part is replica...)
