The GE Fanuc / ICS ICS-115-32 is a 16-bit delta-sigma Digital-to-Analog Converter module for VMEbus systems. It delivers 32 differential analog output channels with high current drivers designed to handle significant capacitive loads. Delta-sigma architecture shifts aliased images away from the signal band, reducing post-filter complexity while maintaining precision through digital interpolation. Each output includes a 2-pole reconstruction filter. The module provides 90 dB dynamic range and -90 dB interchannel crosstalk, with a 1 MSample onboard buffer. Outputs connect via two high-density D-subminiature connectors on the front panel. The module supports external or programmable internal clock operation and integrates directly into VMEbus 6U systems alongside other processor and peripheral modules.
