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 kΩ pull-down resistor when driving lower loads. 3 The 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. 4 GNEG and GPOS, gain control, and voltage range are guaranteed to be within the range of −VS + 4.2 V to +VS − 3.4 V over the full temperature range of −40°C to +85°C. |
