Parameter Description
Parameter Description
Example 4: This example shows a potentiometer range between 0V and 5 V. Instead of adjusting gain
as the example below, the user can set P.38 to 120Hz or P.73 to 0 to achieve the same
result.
Example 5: In this example, a 1V negative bias is used. In a noisy environment, it is advantageous to
use the negative bias to provide a noise margin (1V in this example).
Example 6: In this example, a negative bias is used to provide a noise margin. Also a potentiometer
frequency gain is used to reach the maximum output frequency.
