PIN DESCRIPTIONS (continued)
Description
Gain setting pins. See above table for gain step sizes for each pin. These pins are 3.3V CMOS
logic compatible. 5V inputs may cause damage.
This pin controls the function of the gain setting pins mentioned above. With LATCH in the
logic HIGH state the gain is fixed and will not change. With the LATCH in the logic LOW state
the gain is set by the state of the gain control pins. Any changes in gain made with the LATCH
pin in the LOW state will take effect immediately. This pin is 3.3V CMOS logic compatible. 5V
inputs may cause damage.
This pin is not connected. It can be grounded or left floating.
