Other Parts Discussed in Thread: LMP8602, LMP8601, LMP8603
Thank you Javier for your reply and your advice on the dependency of the input impedance wrt the Vcm. Much appreciated.
One more question is about the figures (Figure49-Figure52) shown on page17.
Although it says OFFSET pin is connected to Vs for these measurements, these figures indicate that the OFFSET pin is actually connected to ground - Vout is close to zero when Vin is negative, Vout vs Vin appear to be linear when the Vin is positive, and when Vin=0, Vout=0 (it would have been 2.5V if OFFSET were connected to 5V)
Also these measurements seem to apply only to LMP8601 which has a gain of 20 rather than LMP8602 and LMP8603.
Do I understand it correctly?
