DescriptionGeneral Standards PMC-16AI64 64-Channel, 16-Bit Analog Input PMC Board | with 500 KSPS Input Conversion RateThe PMC-16AI64 board is a scanning analog digitizer that performs high-speed sampling and 16-bit A/D conversion of as many as 64 single-ended or 32 differential analog input channels. The resulting 16-bit sampled data is available to the PCI bus through a 64K-Sample FIFO buffer. All operational parameters are software configurable.The analog inputs can be sampled in scans of 4, 8, 16, 32 or 64 single-ended channels, or in scans of 4, 8, 16 or 32 differential channels. The scan rate can be controlled internally up to 175,000 scans per second for a 2-channel scan, or any single channel can be sampled at 500,000 samples per second. A Sync input/output signal can replace Channels 62,63 to permit multiple boards to perform synchronous scanning. All inputs are buffered to avoid the high cross talk and input bias currents common with nonbuffered multiplexers.The internal auto calibration utility uses hardware D/A converters to correct for offset and gain errors in the input signal path, and eliminates the missing codes that are inevitably introduced when software correction methods are used. A selftest switching network routes calibration signals through the input multiplexer to the A/D converter to support internal auto calibration, and permits board integrity to be verified by the host. Auto calibration is performed automatically after reset or upon demand from the PCI bus, and calibrates the offset and gain of the converter to a precision internal reference voltage.
