KAD/ADC/134 16 channel Full/1/2-bridge ADC
The KAD/ADC/134 is used to condition and digitize up to 16 differential-ended analog channels. At the heart of the KAD/ADC/134 is a hard-wired state machine that oversamples all channels at a rate between 100 ksps and 200 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). In FIR mode, the IIR filter is bypassed, with samples being outputted directly from the FIR filter. 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/134 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/134 is available with a ±100mV and ±10V input range.
Aerospace Instrumentation Brochure
Modern aerospace instrumentation systems can be highly complex, and it can be difficult to know how to meet program needs. It’s not unusual for requirements to change during a campaign and cause significant delays, and data must be captured reliably no matter what – otherwise expensive additional flights will be needed or months of program data could be lost. Read our brochure to learn how you can reduce your risk with commercial off-the-shelf (COTS) solutions.
