NOTES
1
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.
2
Using resistive loads of 500
Ω
or greater, or with the addition of a 1 k
Ω
pull-down resistor when driving lower loads
3
The dc gain of the main amplifier in the AD600 is X113; thus an input offset of only 100
µ
V becomes an 11.3 mV output offset. In the AD602, the amplifier’s gain is
X35.7; thus, an input offset of 100
µ
V 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
