Gamma curve accuracy includes resistor matching and buffer errors, but excludes the regulator error.
∆V
Total error is the difference between the designed and actual output voltage divided by the actual regulator output voltage or full-scale voltage.
Total error includes regulator error, resistor string error, bias current effects, and buffer offset voltage.
