For higher temperature, the current doubles every 10°C. 4Gain = –4, R L = 2 k Ω, C L = 10 pF. 5Defined as voltage between inputs, such that neither exceeds ± 10 V from common. 6The AD745 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. AD745 ELECTRICAL CHARACTERISTICS |
