KAD/ADC/114 16 channel Full-bridge ADC
16 channel, Full-bridge ADC (voltage excitation, strain gages, 3kHz b/w) - 16ch at 12ksps
The KAD/ADC/114 is used to condition and digitize up to 16 differential-ended analog channels. At the heart of the KAD/ADC/114 is a hard-wired state-machine that oversamples 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 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. Thus, when several channels are sampled at different sampling rates, at the start of an acquisition cycle all channels are aligned.
Excitation on the KAD/ADC/114 is programmable using four D/A converters, each of which is connected to two pairs of drivers. If more than eight excitations are required, each excitation output can be connected to two bridges.
The KAD/ADC/114 is available with three different input ranges (±10V, ±1V, and ±100mV). The input range must be specified when ordering.
