KAM/CDC/101 Charge-to-digital converter (piezoelectric sensors) - 4 channels at 24 ksps

The KAM/CDC/101 is used to digitize signals from charge-based sensors such as piezoelectric devices used for accelerometers. Each is independent and consists of a charge-to-voltage converter (charge-mode amplifier) followed by a second order high pass filter, sixth order low pass filter, programmable gain amplifier, a second order low pass filter and a separate A/D as illustrated in the diagram below.  At the heart of the KAM/CDC/101 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. Unlike most Acra KAM-500 modules, the input connectors are SMC (10-32) sockets for each channel.
