LM2903-Q1 and LM2903B-Q1 Automotive Dual Comparators
Features
Description
•
•
Qualified for automotive applications
The LM2903B-Q1 device is the next generation
version of the industry-standard LM2903-Q1
comparator family. This next generation family
provides outstanding value for cost-sensitive
applications, with features including lower offset
voltage, higher supply voltage capability, lower supply
current, lower input bias current, lower propagation
delay, and improved 2kV ESD performance with drop-
in replacement convenience.
AEC-Q100 qualified with the following results:
– Device temperature grade 0: –40°C to 150°C
ambient operating temperature range
(LM2903E-Q1)
– Device temperature grade 1: –40°C to 125°C
ambient operating temperature range
– Device HBM ESD classification level H1C
– Device CDM ESD classification level C4B
Improved 2 kV HBM ESD for "B" device
Single supply or dual supplies
Low supply-current independent of
supply voltage 200 uA Typ Per
comparator ("B" Versions)
Low input bias current 3.5 nA Typ ("B" device)
Low input offset current 0.5 nA Typ ("B" device)
Low input offset voltage ±0.37 mV Typ ("B" device)
Common-mode input voltage range includes
ground
All devices consist of two independent voltage
comparators that are designed to operate over a wide
range of voltages. Operation from dual supplies also
is possible as long as the difference between the two
supplies is within 2 V to 36 V, and VCC is at least 1.5
V more positive than the input common-mode voltage.
The outputs can be connected to other open-collector
outputs.
