ADG1611 is a four-channel single-pole single-throw switch, and AD620 is an amplifier with a resistance programmable gain. What is the reason for this kind of amplifier with four channels? Are these four resistors?

Used to adjust the external gain.

You can control these switches to control the resistance Rg, thereby controlling the external gain.

By combining different resistance values on different switches to change Rg to change the gain.
