KAD/ADC/116 Accelerometer ADC (current excitation, programmable analog gain, 3 kHz b/w) – 12 channels at 12 ksps
The KAD/ADC/116 is used to condition and digitize up to 12 accelerometer-type input channels. Each of these channels has a constant current source and AC coupled (DC-reject) inputs for use with integrated charge-amp piezoelectric accelerometer devices.
At the heart of the KAD/ADC/116 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. This means that even when several channels are sampled at different sampling rates, the sample at the start of the acquisition will always be synchronized.
