Hi,
I want to know if there is any way to calculate/Measure/Simulate the linearity of the device?
A customer is using LMP7732 THS4520 for their low pass filter design and they have specified their requirement as :
drift <100ppm/K, <100ppm/month (abs linearity < 0.1% INL supposed)
What is the significance of these limits in determining the linearity?
Hi Riddhee,
hard to answer without seeing the circuit. But a distortion measurement with sine waves should work.
Don't overlook the influence of capacitor, inductor and resistor properties on drift and linearity! What type of caps, inductors and resistors are you planning to use?

Hello Kai,
I am attaching the TINA simulation file of the test circuit. How to see the effect of capacitors and resistors ?3404.Schematic.TSC
