The KAD/ADC/106 is used to condition and digitize up to eight differential-ended analog channels. Six of these channels have a constant current source.
- Six accelerometer input channels with DC-reject and two differential ended input channels
- Accelerometer input programmable range (±1V, ±10V)
- Differential ended input programmable range (±10mV to ±10V)
- Constant current source excitation on each accelerometer input channel (3.6mA typical)
- Short on any channel does not affect others
- 16 bit simultaneous sampling on each channel
- Up to 24k samples per second per channel
- Up to 6 kHz Bandwidth (AAAF filter)
- Accelerometer signal conditioning and digitalization
- Suitable for Integrated Circuit Piezoelectric (ICP), Isotron, Piezotron, and Deltatron sensors
- Differential voltage measurement
KAD/ADC/106 Accelerometer ADC
The KAD/ADC/106 is used to condition and digitize up to eight differential-ended analog channels. Six of these channels have a constant current source and high-pass (DC-reject) filter for use with ICP accelerometer devices.
At the heart of the KAD/ADC/106 is a hard-wired state machine that oversamples all channels at a rate between 96 ksps and 192 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 (isochronously). Thus, when several channels are sampled at different sampling rates, at the start of an acquisition cycle all channels are aligned.
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.
