18AI32SSC1M

Overview

18-Bit, 32-Channel, Differential, 1.0 MSPS, Simultaneous Sampling PMC Analog Input Board

The PMC66-18AI32SSC1M analog input board from General Standards samples and digitises up to 32 input channels simultaneously at rates up to 1,000,000 samples per second for each channel.

The board can be used on PCI Express, PCI-X, cPCI-X, PCI, cPCI, PC/104-Plus via an adapter, and is functionally compatible with the IEEE PCI local bus specification Revision 2.3. System connections are made through a high-density front-panel I/O connector. Power requirements consist of +5 VDC in compliance with the PCI specification, and operation over the specified temperature range is achieved with standard convection cooling.

Typical Applications
High-Accuracy Analog Inputs
Industrial Robotics
Acoustic Sensor Arrays
Analog Event Capture
Biometric Signal Analysis
Dynamic Test Systems

Technical

32 Differential Analog Inputs with dedicated 1.0MSPS SAR 18-Bit ADC per channel; Exceptional combination of precision, throughput and channel density on PMC
Simultaneous Sampling of all inputs; minimum data skew
Sampling rates from zero to 1.0 MSPS per channel (32 MSPS aggregate rate)
True Differential inputs minimise input noise and system interference
Input ranges: +/-10V, +/-5V, +/-2.5V software-selectable
256 K-Sample FIFO data buffer
SAR (successive approximation) ADCs provide true simultaneous sampling without a minimum sample rate limitation
D32; 66MHz/33MHz PCI compatibility, with universal 5V/3.3V signaling
2-Channel DMA engine supports both block and demand mode DMA transactions
Sampling controlled by an internal rate generator, by a software trigger, or externally
Continuous, burst and single-sample clocking modes
Hardware sync I/O for multiboard operation through both front-panel and internal ports
On-Demand internal autocalibration of all channels
Completely software-configurable; No field jumpers
Single-width PMC form factor with integral EMI shield
Available also with 16-Bit resolution at reduced cost
