KAD/ADC/109/QB350 ¼-bridge 350Ω ADC (current excitation, programmable analog gain, 6 kHz b/w) - 8 channels at 24 ksps
The KAD/ADC/109/QB350 provides independent excitation for up to eight channels and is intended for ¼-bridge 350Ω strain gage type applications. Each channel has a separate programmable amplifier, programmable filter and A/D converter.
At the heart of the KAD/ADC/109/QB350 is a hard-wired state-machine that over-samples 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, decimate by 2, 15 tap, Finite-Impulse-Response (FIR) filters with 32-bit coefficients followed by an 8th order Butterworth IIR filter with a default cutoff point set at a quarter of the sampling frequency.
The current through the gage is programmable (to approximately 14.5 mA in 5 µA steps) and is kept constant. As the resistance changes, the voltage across the gage (and hence as seen by the amplifier) changes linearly.
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 is always synchronized.
