Figure 40 shows the gain vs. VGN for the circuit in Figure 39
at 1 MHz and the lowest gain range (−14 dB to +34.4 dB). Note
that the gain scaling is 40 dB/V, double the 20 dB/V of an
individual DSX; this is the result of the parallel connection of
the gain control inputs, VGN1 and VGN2. The gain can also be
sequentially increased by first increasing the gain of Channel 1
and then Channel 2. In this case, VGN1 and VGN2 are driven
from separate voltage sources, for instance two separate DACs.
Figure 41 shows the gain error of Figure 39.
