Other Parts Discussed in Thread: OPA140, LM6142
Dear forum members and support team,
I'm using LM6144 in my design. One op amp (AOP1) is used as an inverting amplifier with RF=RI=22k.
AOP1 output is wired to an active low pass filter implemented with the three last op-amps of the LM6144 device.
Instead of having 0V on the inverting input of AOP1 I have an oscillation as shown below.
Could this be related to input capacitance? If yes where can I find Ccm+, Ccm-, and Cdiff values?
Thanks for your help. Best regards.
Benoît,
