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. One could of course
also sequentially increase the gain 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.
