5.6 Electrical Characteristics LM2903B

VS = 5V, 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
Input offset voltage, DGK package only VS = 5 to 36V -3.5 ±0.37 3.5
VS = 5 to 36V, TA = –40°C to +125°C -5 5
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;

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 = 5V; 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 = 5V, no load 400 600 µA
VS = 36V, no load, TA = –40°C to +125°C 550 800 µA
(1) The voltage at either input can not be allowed to go negative by more than 0.3V otherwise output can be incorrect and excessive
input current can flow. The upper end of the common-mode voltage range is limited by VCC – 2V. However only one input needs to be
in the valid common mode range, the other input can go up the maximum VCC level and the comparator provides a proper output state.
Either or both inputs can go to maximum VCC level without damage.
