Typical open or short-circuited input; noise is lower when system is set to maximum gain and input is short-circuited. This figure includes the effects of both voltage
and current noise sources.
Using resistive loads of 500 Ω or greater or with the addition of a 1 kΩ pull-down resistor when driving lower loads.
The dc gain of the main amplifier in the AD603 is ×35.7; therefore, an input offset of 100 μV becomes a 3.57 mV output offset.
GNEG and GPOS, gain control, and voltage range are guaranteed to be within the range of −V
