CompactPCI Boards AcPC330 16-bit A/D Analog Input AcPC330 boards provide fast, high resolution A/D conversion. The AcPC330 has many features to improve your overall Advanced memory management techniques allow the AcPC330 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 CompactPCI bus Compliance Specifications scans selected channels at the maximum conversion Meets PCI spec.

Uniform mode performs conversions at user- Analog Input Data transfer bus: Slave with 32-bit, 16-bit, and 8-bit data Input configuration: 16 differential or 32 single-ended defined intervals. Both modes can scan continuously, or transfer operation.. channels. execute a single cycle upon receiving a trigger. Interrupts (INTA#): Interrupt A is used to request an interrupt. A/D resolution: 16 bits. Plug-and-Play: The system maps the base address into the “Mail box”memory allows the CPU to read the latest Input ranges: ±5V, ±10V, 0-5V, and 0-10V.
