The KAD/CDC/002 is used to condition and digitize up to 24 differential-ended current channels. At the heart of the KAD/CDC/002 is a hard-wired state-machine that over-samples all channels and digitally filters any noise above the user-programmable cutoff frequency. This is achieved using cascaded, half-band, decimate by 2, 15-tap, Finite-Impulse-Response (FIR) filters with 32-bit coefficients. All signals are sampled simultaneously. Secondary gain and offset are achieved digitally according to a specified range.
