I am designing instrumentation amplifier with differential input voltage equal to 400 mv, I used a source degeneration resistor to increase this range. do you think it is good range?
Can you please suggest me some of the available commercial instrumentation amplifier in order to compare
If you know output signal range desired and gain,
you get the differential input range.
Distinguish between "amplify clean" and "tolerate,
with loss of fidelity" regarding the differential input
range, and do not neglect the common mode bind
which may change as you attempt to raise signal
range. The internal amps each have their limits and
the A=2 front end amp particularly can be a problem
for high input levels, clipping at its output.
I am getting +-400mV linear and clean differential level, only have a problem when the gain is set to unity I can see clipping, otherwise it is working fine from Gain = 2 and more, soon I will show you the result graphs,
do you think it is good result even when the amp is not working with unity gain ?
