For higher temperature, the current doubles every 10°C. 4Gain = –1, RL = 2 kΩ, CL = 10 pF. 5Defined as voltage between inputs, such that neither exceeds ±10 V from common. 6The AD743 does not exhibit an output phase reversal when the negative common-mode limit is exceeded. All min and max specifications are guaranteed. Specifications subject to change without notice. –2– REV.
