Description
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 dropin
replacement convenience.
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.
The LM2903-Q1 and LM2903B-Q1 are qualified for
the AEC-Q100 Grade 1 temperature range of -40°C to
+125°C. The LM2903E-Q1 is Qualified for the Grade
0 extended temperature range of -40°C to +150°C.
