NOTES

1Typical 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.

2Using resistive loads of 500

Ω or greater, or with the addition of a 1 kΩ pull-down resistor when driving lower loads.

3The dc gain of the main amplifier in the AD603 is

×35.7; thus, an input offset of 100 µV becomes a 3.57 mV output offset.

4GNEG and GPOS, gain control, voltage range is guaranteed to be within the range of – V

S + 4.2 V to +VS – 3.4 V over the full temperature range of –40 °C to +85°C.

Specifications shown in boldface are tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels. All min

and max specifications are guaranteed, although only those shown in boldface are tested on all production units.

Specifications subject to change without notice.
