1. INTRODUCTION
1.1 CHOICE OF MODELS
ADAC/5500 PCI Series cards are part of an extensive line of data acquisition boards for use in PCs. ADAC series
boards are low cost and are optimized for use with Windows. We offer “sensor specific” DIRECT CONNECT
™
boards, isolated digital I/O boards, boards for DSP applications, and much more. Visit our web site to learn about our
complete line of products.
1.2 PRODUCT DESCRIPTION ADAC/5500 SERIES
The ADAC/5500 Series includes several models of data acquisition boards. These are discussed briefly below, and in
the preceding table. Pages 2 and 3 consist of block diagrams to provide a better understanding of board function.
The ADAC/5500MF has 8 single-ended analog inputs multiplexed to a 12-bit A/D converter with maximum
throughput of 100 kHz, two counter input channels, two timer output channels and 16 lines of digital I/O.
The ADAC/5501MF has 16 single-ended/pseudo-differential or 8 differential analog inputs multiplexed to a 12-bit
A/D converter with maximum throughput of 100 kHz, programmable gains of 1, 2, 4 or 8, two optional clocked 16-bit
D/A voltage outputs, two counter input channels, two timer output channels and 48 lines of digital I/O.
The ADAC/5502MF is the same as the ADAC/5501MF, but with programmable gains of 1, 10, 100 or 1000.
The ADAC/5503HR has 16 single-ended/pseudo-differential or 8 differential analog inputs multiplexed to a 16-bit
A/D converter with maximum throughput of 200 kHz, programmable gains of 1, 2, 4 or 8, two optional clocked 16-bit
D/A voltage outputs, two counter input channels, two timer output channels and 48 lines of digital I/O.
The ADAC/5504HR is the same as the ADAC/5503HR, but with programmable gains of 1, 10, 100.
V-versions of the boards include two clocked DACs, with exception of ADAC/5500MF, which has no “V”- version
counterpart.
All boards feature on-board digital calibration for both A/D and D/A, and a DMA engine for optimum performance in
a Windows environment. Board connections are terminated in a 68-pin “high density” SCSC III connector at the rear of
the PC.
