3 Description
The LM358B and LM2904B devices are the
next-generation versions of the industry-standard
operational amplifiers (op amps) LM358 and LM2904,
which include two high-voltage (36 V) op amps.
These devices provide outstanding value for costsensitive
applications, with features including low
offset (300 μV, typical), common-mode input range to
ground, and high differential input voltage capability.
The LM358B and LM2904B op amps simplify circuit
design with enhanced features such as unity-gain
stability, lower offset voltage maximum of 3 mV (2 mV
maximum for LM358BA and LM2904BA), and lower
quiescent current of 300 μA per amplifier (typical).
High ESD (2 kV, HBM) and integrated EMI and RF
filters enable the LM358B and LM2904B devices to be
used in the most rugged, environmentally challenging
applications.
The LM358B and LM2904B amplifiers are available
in micro-sized packaging, such as the SOT23-8, as
well as industry standard packages including SOIC,
TSSOP, and VSSOP.
