V 25°C 2 5 V CC = 5 V to 30 V, VO = 1.4 V, VIC = V IO Input offset voltage mV IC(min) Full range 9 25°C 5 50 IIO Input offset current VO = 1.4 V nA Full range 250 25°C –25 –250 IIB Input bias current VO = 1.4 V nA Full range –400 Common-mode input voltage 0 to V V CC – ICR V range(2) Full range 1.5 Large-signal differential voltage V A CC = 15 V, VO = 1.4 V to 11.4 V, R VD 25°C 50 200 V/mV amplification L ≥ 15 kΩ to VCC VOH = 5 V, VID = 1 V 25°C 0.1 50 nA IOH High-level output current VOH = 30 V, VID = 1 V Full range 1 μA 25°C 150 400 VOL Low-level output voltage IOL = 4 mA, VID = –1 V mV Full range 700 IOL Low-level output current VOL = 1.5 V, VID = –1 V 25°C 6 mA ICC Supply current RL = ∞, VCC = 5 V 25°C 0.4 0.7 mA (1) All characteristics are measured with zero common-mode input voltage, unless otherwise specified. (2) The voltage at either input or common-mode should not be allowed to go negative by more than 0.3 V. The upper end of the common- mode voltage range is VCC+ – 1.5 V, but either or both inputs can go to 30 V without damage. (3) Full range TA is –40°C to +85°C for I-suffix devices and –40°C to +105°C for K-suffix devices.
