PCI-DAS4020/12

Ultra High Speed 12-bit analog input board

Overview

The PCI-DAS4020/12 is an ultra high speed, analog input board for PCI bus computers. It provides four, 12-bit analog inputs with sample rates up to 20 MHz, 24 bits of digital I/O, and two, 12-bit analog outputs.

Central to the board is a powerful System Timing Controller (STC) chip. The STC controls all A/D sampling including a 64K sample A/D FIFO. This functionality is based on the STC use of an on-board 32K x 24 SRAM. The board provides bus-mastering and scatter-gather functionality to assure the desired system timing is maintained.

The PCI-DAS4020/12 is completely plug-and-play. There are no switches, jumpers, or potentiometers on the board. All board addresses, interrupt channels etc. are set by your computer’s plug-and-play software. Even calibration is performed via software by using on-board digital potentiometers and trim D/A converters
