1 The AD8230 can operate as low as G = 2. However, since the differential input range is limited to approximately 750 mV, the AD8230 configured at G < 10 does not
make use of the full output voltage range.
2 Gain drift is determined by the TC match of the external gain setting resistors.
3 Differential source resistance less than 10 kΩ does not result in voltage offset due to input bias current or mismatched series resistors.
4 For G < 10, the reference voltage range is limited to VS + 4.24 V to +VS 2.75V.
