Industry Pack Modules IP220A-x 12-Bit D/A, Analog Output The IP220A outputs analog voltage signals to drive up to 16 devices. When used with a carrier that holds four IP modules, up to 64 voltage outputs can be obtained from a single card cage slot. The IP220A features individual D/A converters on each channel for better performance. Each output channel has its own 12-bit D/A converter Specifications Ordering Information (DAC). Individual DACs are faster, and they eliminate glitches typically caused by the re-acquisition process of Analog Outputs Industry Pack Modules Output configuration: 8 or 16 single-ended. sample and holds found on multiplexed output boards.
