Determining Optimal Gain and Offset Codes
First, determine the desired gain:
1. Determine the desired gain, GA (using the measurements
obtained from the simulation).
that (2.8 × 1.05) < (GA/G2) < (5.2/1.05). This ensures the
first and last codes for the first stage gain are not used,
thereby allowing enough first stage gain codes within each
second stage gain range to adjust for the 3% accuracy.
Next, set the second stage gain:
1. Use the simulation mode to set the second stage gain to G2.
2. Set the output offset to allow the AD8557 gain to be
measured, for example, use Code 128 to set it to midsupply.
3. Use Table 6 or Equation 1 to set the first stage gain code
CG1, so the first stage gain is nominally GA/G2.
4. Measure the resulting gain (GB). GB should be within
3% of GA.
5. Calculate the first stage gain error (in relative terms)
EG1 = GB/GA 1.
6. Calculate the error (in the number of the first stage gain
codes) CEG1 = EG1/0.00489.
7. Set the first stage gain code to CG1 CEG1.
8. Measure the gain (GC). GC should be closer to GA than to GB.
9. Calculate the error (in relative terms) EG2 = GC/GA 1.
10. Calculate the error (in the number of the first stage gain
codes) CEG2 = EG2/0.00489.
11. Set the first stage gain code to CG1 CEG1 CEG2. The
resulting gain should be within one code of GA.
Finally, determine the desired output offset:
1. Determine the desired output offset OA (using the
measurements obtained from the simulation).
2. Use Equation 2 to set the output offset code CO1 such that
the output offset is nominally OA.
3. Measure the output offset (OB). OB should be within
3% of OA.
4. Calculate the error (in relative terms) EO1 = OB/OA 1.
5. Calculate the error (in the number of the output offset
codes) CEO1 = EO1/0.00392.
6. Set the output offset code to CO1 CEO1.
7. Measure the output offset (OC). OC should be closer to OA
than to OB.
8. Calculate the error (in relative terms) EO2 = OC/OA 1.
9. Calculate the error (in the number of the output offset
codes) CEO2 = EO2/0.00392.
10. Set the output offset code to CO1 CEO1 CEO2. The
resulting offset should be within one code of OA.
