The KAD/TDC/101 provides independent excitation for up to 16 channels and is intended for 10kΩ thermistor type sensors. Each channel has a separate programmable digital filter and A/D converter.
At the heart of the KAD/TDC/101 is a hard-wired state-machine that oversamples all channels at a rate between 100ksps and 200ksps 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 IIR filter with a default cutoff point set at one quarter of the sampling frequency (fc = fs / 4).
