Notes to table at left: * Exceeding these throughputs may result in inaccurate dynamic measurements. **In simultaneous mode, both A/D converters operate at the same time, sampling two channels at once. Each A/D converter is capable of 100 kS/s, for an aggregate throughput of 200 kS/s. In pseudo-differential mode, both the signal +in and -in are connected to separate multiplexer channels. However, unlike conventional differential circuits, only the +in side is sampled. This requires that the -in side remain stable to within 0.5 LSB during conversion.

data transfers to occur totally asynchronously with A/D operation D/A (DT7102 only)-- D/A data values pass from the PC Card Interface via a 512sample FIFO. This allows data transfers to occur totally asynchronously with D/A operation OPERATING MODES A/D Channel Selection-- single channel channel scan Operating Modes-- single conversion; continuous conversions Simultaneous Sampling (DT7102 only)--the DT7102 supports simultaneous sampling on pairs of input channels; in this mode, the board's two A/D converters run simultaneously,
