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.

Example 3 — Min

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.
