The MCAS-104D-3 is a 4-channel single-ended piezo-electric accelerometer signal conditioning module for use in Curtiss-Wright’s MEDAU-20xx, MCDAU-20xx, or MWDAU-20xxX series products. Each input channel provides a charge amplifier for interfacing with a single-ended piezo-electric accelerometer. The module then provides software programmable gain, programmable offset and programmable, DSP-based, presample filtering per channel.
