Figure 4 showcases the setup for three commonly used
resolutions: 1600 x 1200, 1280 x 1024, and 1024 x 768.
Since the resolution change is relatively slow, the
switch does not have to be fast. The impedance of the
switch does not need to be low compared to R
RX
.
When using a high-impedance switch, the resistance
from the switch should be included to calculate R
RX
.
The MAX4731 50
SPST analog switch shown in the
figure is used with three external resistors to get R
RX
values of 47k
, 23.5k
, and 10k
for 1600 x 1200,
1280 x 1024, and 1024 x 768 resolutions, respectively.
