Gain Resistor Determination

Replacing a single resistor changes the gain on each buffer. Change R1 to modify the gain on channel A, R2 to change channel B, R7 to change channel C, and R8 to change channel D. Use Equation 8 to determine the value of the gain resistor to attain a calculated gain. To use this gain value, place the gain jumper corresponding to the correct channel in the User/22.28 position. JP1 corresponds to channel A, JP2 corresponds to channel B, JP3 corresponds to channel C, and JP4 corresponds to channel D.

RG is the value of the gain resistor in ohms.

Example: Find the appropriate 1% resistor for a maximum gain of 150 and calculate the actual gain.

From Equation 8: RG =

100000

(150

1)

= 671.141

 

 

 

The nearest 1% resistor that will produce a gain of 150 or less is 681Ω.

From Equation 9: G =

1 + 100000

681

= 147.8

 

 

 

The nearest 1% resistor is 681

with a resulting gain of 147.8.
