Today I bought a MAX038 function generator, but after trying it with 3 different test circuits the IC doesn't seem to work properly.
For example, I tried it with the circuit below -which is one that comes in the datasheet- and the most I get is only a sort of a sine/saw wave of 200mVpp, offset +0.5V, and at a frequency much higher than what it should.
I also noticed that it doesn't work when you supply it exactly ±5V; it would only work from ±5.14V to ±5.35V and any tiny difference in supply voltage will have a huge effect on output amplitude and frequency.
I would appreciate if anyone could advice me on how to test the IC properly to make sure it's not damaged. Thanks.
