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+) = V= 5 V; VID = 1V  0.1 20 nA
(V+) = V= 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
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.
