The throughput for channel-to-channel sampling with fixed gain in
unipolar mode (0.024% maximum error) is as shown in Table 2-4.
The maximum throughput for a DAS-1801HC, operating in bipolar mode
and having less than 1 LSB of error when driven from an ideal voltage
source, is as shown in Table 2-5.
