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 AD600 is X113; thus an input offset of only 100 μV becomes an 11.3 mV output offset. In the AD602, the amplifier’s gain is X35.7; thus, an input offset of 100 μV becomes a 3.57 mV output offset.

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

Specifications subject to change without notice.
