PMC Modules PMC330 16-Bit A/D Analog Input PMC330 mezzanine modules provide fast, high resolution A/D conversion. The PMC330 has many features to improve your overall Advanced memory management techniques allow the PMC330 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 Environmental Specifications scans selected channels at the maximum conversion Operating temperature: 0 to 70°C (PMC330) rate. Uniform mode performs conversions at user- Analog Inputs or -40 to 85°C (PMC330E model) Input configuration: 16 differential or 32 single-ended. defined intervals. Both modes can scan continuously, or Storage temperature: -55 to 100°C (all models). execute a single cycle upon receiving a trigger. A/D resolution: 16 bits.
