Note 3: Minimum and maximum parameters are not tested. Guaranteed by design.

Note 4: Input resistance varies inversely with sample rate.

Note 5: Calibration remains valid for temperature changes within ±20°C and power-supply variations ±5%.

Note 6: All AC specifications are shown for the differential mode.
