Note 5. Gain value for each gain setting is measured as AC measurement relative to GABS assuming a gain step size of 0.5dB. Gain
settings 65…255 are tested in production. Gain error for lower gain settings is guaranteed by design only.
Note 6. Gain mismatch is tested in production for gain settings 90…255. Mismatch for lower gain settings is guaranteed by design only.
