PMC330: Analog Input Module, 16-bit A/D

PMC330 mezzanine modules provide fast, high resolution A/D conversion.

The PMC330 has many features to improve your overall system throughput rate. You can scan all channels or define a subset for more frequent sampling. Burst mode scans selected channels at the maximum conversion rate. Uniform mode performs conversions at user-defined intervals. Both modes can scan continuously, or execute a single cycle upon receiving a trigger.

“Mail box” memory allows the CPU to read the latest data in 32 storage buffer registers without interrupting the A/D converter.

Specifications

Analog Inputs

Input configuration: 16 differential or 32 single-ended.
A/D resolution: 16 bits.
Input ranges: ±5V, ±10V*, 0-5V, and 0-10V*. * Requires ±15V external supplies.
