3.10 Electrical Characteristics LM2903B - Q1

VS = 5 V, VCM = (V–) ; TA = 25°C (unless otherwise noted).
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
VIO Input offset voltage VS = 5 to 36V –2.5 ±0.37 2.5 mV
VS = 5 to 36V, TA = –40°C to +125°C –4 4 mV
VIO Input offset voltage, DGK package only VS = 5 to 36V –3.5 ±0.37 3.5 mV
VS = 5 to 36V, TA = –40°C to +125°C –5 5 mV
IB Input bias current –3.5 –25 nA
TA = –40°C to +125°C –50 nA
IOS Input offset current –10 ±0.5 10 nA
TA = –40°C to +125°C –25 25 nA
VCM Common mode range(1) VS = 3 to 36V (V–)  (V+) – 1.5 V
VS = 3 to 36V, TA = –40°C to +125°C (V–)  (V+) – 2.0 V
AVD Large signal differential voltage amplification VS = 15V, VO = 1.4V to 11.4V;
RL ≥ 15k to (V+)		 50 200 V/mV
VOL Low level output Voltage {swing from (V–)} ISINK ≤ 4mA, VID = -1V 110 400 mV
ISINK ≤ 4mA, VID = -1V
TA =  –40°C to +125°C		 550 mV
IOH-LKG High-level output leakage current (V+) = VO = 5 V; VID = 1V  0.1 20 nA
(V+) = VO = 36V; VID = 1V 0.3 50 nA
IOL Low level output current VOL = 1.5V; VID = -1V; VS = 5V 6 21 mA
IQ Quiescent current (all comparators) VS = 5 V, no load 400 600 µA
VS = 36 V, no load, TA = –40°C to +125°C 550 800 µA
(1) The voltage at any input should not be allowed to go negative by more than 0.3 V. The upper end of the input voltage range is VCC − 1.5 V for one input, and the other input can exceed the VCC level; the comparator provides a proper output state. Either or both inputs can go to 36 V without damage.
