In Example 2, the Output also changes at a rate of 32767 units-per-second. The Input level
here is only 16383, but input Gain has doubled.

INTEGRATOR Input
B
In Example 3, the Max and Min input limits have been set at
±
16383 and the Output is
clamped accordingly. The internal accumulator is also held at these limits and not allowed to
accumulate beyond these limits. This allows the Output to come out of it’s limits as soon as
the input moves in the negative direction.
