The KAD/TDC/102 is used to condition and digitize up to fifteen thermocouple channels and three channels of module junction temperature. Each thermocouple channel can be configured separately for use with a wide range of thermocouple types.  

Together, the KAD/TDC/102 and the CON/KAD/010 connector use the preconfigured module junction temperature channels 0 and 2, to perform linearization and cold junction compensation for each thermocouple channel.  At the heart of the KAD/TDC/102 is a hard-wired state machine that oversamples all channels at a rate up to 50 ksps and digitally filters any noise above the user-programmable cutoff frequency.  

This is achieved using cascaded, half-band, Finite-Impulse-Response (FIR) filters followed by an 8th order Butterworth Infinite-Impulse-Response (IIR) filter with a default cutoff point set at one-quarter of the sampling frequency (fc = fs/4).   All signals are sampled simultaneously. When several channels are sampled at different sampling rates, at the start of an acquisition cycle, all channels are aligned.
