The KAD/ADC/112 is used to condition and digitize up to 24 D/E analog channels. At the heart of the KAD/ADC/112 is a hard-wired state machine that over-samples all channels at a rate between 48 ksps and 96 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 IIR filter with a default cutoff point set at one-quarter of the sampling frequency (fc = fs/4). All signals are sampled simultaneously. Thus, when several channels are sampled at different sampling rates, at the start of an acquisition cycle all channels will be aligned.

The KAD/ADC/112 is available with four different input ranges (±40V, ±10V, ±1V, ±100mV). The input range must be specified when ordering.


  • 24 differential ended input channels
  • Ordering input range of ±100mV to ±40V
  • High accuracy (0.01% FSR typical)
  • High input resistance (>1MΩ) when on/off for /100mV, /1V, and /10V variant
  • 16-bit simultaneous sampling on each channel
  • Up to 4k samples per second per channel
  • Up to 1kHz Bandwidth (AAAF filter)
