PCI Boards APC330 16-bit A/D Analog Input APC330 boards provide fast, high resolution A/D conversion. The APC330 has many features to improve your overall Advanced memory management techniques allow the APC330 to operate with minimal interruption of the A/D converter. system throughput rate. You can scan all channels or define a subset for more frequent sampling. Burst mode PCI Bus Compliance Specifications scans selected channels at the maximum conversion This device meets or exceeds all written PCI local bus rate. Uniform mode performs conversions at user- Analog Input specifications per rev. 2.2 dated December 1998. Input configuration: 16 differential or defined intervals. Both modes can scan continuously, or System base address: This board operates in memory space.
