Chapter 4 Functional Details Analog input resolution and range The 16-bit A/D converter provides a resolution of 1/65,536 parts of full scale. The smallest reading of full scale (1 part in 65,536) is called a Least Significant Bit (LSB). Four different bipolar ranges are controlled by software: Analog input ranges Bipolar 1 LSB ±10 V 0.000305 V ±5 V 0.000153 V ±2.5 V 0.000076 V ±1.25 V 0.000038 V The input range is controlled by a programmable-gain amplifier.

PC-CARD-DAS16/16AO User's Guide Functional Details After a conversion is made, the sample is stored in 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 does the FIFO size and design affect throughput? The 4096-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 is ready, the FIFO is emptied into system memory. Most FIFO designs empl
