Description
R_fdbk = 21.787
R_input = 20
Fixed input resistor
Gain_Binary_OA: = R_fdbk / R_input
Gain_Binary_OA = 1.089 versus Gain_Required = 1.083
Comparing the “Binary Gain
Amp” to the “Calculated
Required Gain”
Per_Cent_Gain_Error: = (Gain_Binary_OA -
Gain_Required / Gain_Required) x 100
Per_Cent_Gain_Error = 0.57
The error is now less than 1%.
