10.2.1.3.1 DC Performance

The measured dc performance and calculated error of the circuit is shown in Figure 20 and Figure 21, respectively. By applying a two-point gain and offset calibration over the specified ±5-V input range, the calibrated error is shown in Figure 22. The uncalibrated results show errors of 138 μV, or 0.0138%FSR. The calibrated results with a simple two-point calibration show errors under 5 μV, or 0.0005%FSR, in the specified input range of ±5 V.
