4. 1 0 LSB max Integral linearity error 5 0 LSB max Each PC CARD DAS16 12A0 is tested at the factory to assure the board s overall error does not exceed 5 0 LSB Total board error is a combination of gain offset integral linearity and differential linearity error The theoretical worst case error of the board may be calculated by summing these component errors Worst case error is realized only in the unlikely event that each of the component errors are at their maximum level and causing error in the same direction Although an examination of the chart and a summation of the maximum theoretical errors shows that the board could theoretically exhibit a 7 5 LSB error our testing assures this error is never realized in a board that we ship Coding Inverted Offset Binary 0 code FS 4095 code FS Output voltage on power up and reset 10 V FS 22 PC CARD DAS16 12AO User s Guide Specifications Digital input output Table 9 DIO specifications Digital type FPGA Number of 1 0 Configuration One port programmable 4 input 4 output Interrupt Table 10 Interrupt specifications Counter Table 11 Counter specifications Counter type 82C54 Configuration 3 down counters 16 bits each Counter 1 User counter Source Programmable external Ctr 1 Clk or 100kHz internal source Gate Available at connector Ctr 1 Gate pulled to logic high via 10K resistor See Note 2 Output Available at c
5. 12A0 programmable pacer software or external The trigger source selection is programmable The programmable pacer is the product of two 16 bit counters dividing a 10 MHz or I MHz pulse derived from a 10 MHz crystal oscillator which can be used to trigger any number of paced conversions single conversion can be triggered by software at any time External trigger pacer clock and interrupt signals may also be used to control conversions and synchronize to external events After a conversion is made the sample is routed to a 4096 word sample FIFO buffer from which it may be retrieved one sample at a time or in blocks via REP INSW transfers How do FIFO size and design affect throughput The 4096 12 bit sample FIFO buffer stores samples from the A D converter as they are being converted When a block of samples is ready and when the PC 1s ready the FIFO is emptied into system memory Most FIFO designs employ a half full transfer initiation circuit When the FIFO is half full the transfer request 1s made Samples continue to fill the second half of the FIFO while the CPU responds to the transfer request and transfers data to system memory A D pacer clock Many analog acquisitions can be handled by a simple on board rate divider created by combining a crystal oscillator with a programmable counter For those the on board 82C54 programmable rate generator counter supplies the pacing Some applications require more flexible rate control
6. The PC CARD DAS16 12A0 analog conversions can be externally paced and thereby synchronized with events external to the PC Conversions can be held off until some external event such as a not to exceed condition is met Conversions can be externally gated so that samples are taken only when an event of interest is occurring such as a process going over normal limits Figure 9 shows a logic diagram of the A D pacer clock and counters 18 PC CARD DAS16 12A0 User s Guide Functional Details Control Register BASE 6h TRGPOL TRGSEL TRGCLR CLK2 CTR1 CRT1 CLK 10K CTR1 GATE pe 1 GATE I OUT DDL et om or CLK l l CLK I IOUT A D INTERNAL E Gomer PACER OUT 44 A D PACER GATE A D EXTERNAL TRIGGER CLK Trigger TS1 TSO Control register BASE 4h A D Convert CLock A D EXTERNAL CLOCK Trigger Logic S W CONVERT Figure 9 Counter pacer logic diagram 19 Chapter 5 Specifications Typical for 25 C unless otherwise specified Specifications in italic text are guaranteed by design Analog input Table 1 Analog input specifications A D converter type ADS7804 Number of channels 16 single ended 8 differential software selectable Input ranges 10 V 5 V 12 5 V 1 25 V 0 to 10 V 0 to 5 V 0 to 2 5 V 0 to 1 25 V software programmable A D pacing Internal counter 82C54 software programmable External source A D External Pacer software p

27. y 50 us What factors limit conversion speed The first is clearly the A D A 10 us conversion speed translates to a maximum throughput of 100 kHz The second limiting factor can be the analog front end The front end may consist of a multiplexer and a programmable gain amplifier The speed at which these circuits can switch may also limit the throughput of the A D board That is the rate at which it can acquire convert and transfer a signal with full accuracy Accuracy is the key term here The A D can always run at full speed but has the front end settled and captured a true accurate signal What about input range vs speed Here is where the design of the analog front end is critical to maintaining total throughput Most A D converters have a fixed input range typically 5V It is the analog front end that amplifies low level signals and adjusts unipolar signals to match the A D converter s standard input A poorly designed analog front end will show up very quickly in the throughput specifications If you see that an A D board has high throughput in only one or two ranges but is slowed greatly at all other ranges you are seeing the practical implications of a poor front end design The PC CARD DAS16 12A0 achieves 100 kHz in all of the eight ranges 17 PC CARD DAS16 12A0 User s Guide Functional Details Triggering and transfer trigger begins an acquisition transfer cycle There are three ways to trigger a PC CARD DAS16
