3 Description
The LM2904-Q1 and LM2904B-Q1 are industry-
standard operational amplifiers that have been
qualified for automotive use in accordance to the
AEC-Q100 specifications. The LM2904B-Q1 is the
next-generation version of the LM2904-Q1, which
include two high-voltage (36 V) operational amplifiers
(op amps). The LM2904B-Q1 provides outstanding
value for cost-sensitive applications, with features
including low offset (1 mV, typical), common-mode
input range to ground, and high differential input
voltage capability.
The LM2904B-Q1 simplifies circuit design with
enhanced features such as unity-gain stability, lower
offset voltage of 1 mV (typical), and lower quiescent
current of 300 µA (typical). High ESD (2 kV, HBM) and
integrated EMI and RF filters enable the LM2904B-Q1
devices
to
be
used
in
the
most
rugged,
environmentally challenging applications for the
automotive marketplace.
