3 Description

The LM324B and LM2902B devices are the

next-generation versions of the industry-standard

operational amplifiers (op amps) LM324 and LM2902,

which include four high-voltage (36 V) op amps.

These devices provide outstanding value for costsensitive

applications, with features including low

offset (600 μV, typical), common-mode input range to

ground, and high differential input voltage capability.

The LM324B and LM2902B op amps simplify circuit

design with enhanced features such as unity-gain

stability, lower offset voltage maximum of 3 mV (2 mV

maximum for LM324BA and LM2902BA), and lower

quiescent current of 240 μA per amplifier (typical).

High ESD (2 kV, HBM) and integrated EMI and RF

filters enable the LM324B and LM2902B devices to be

used in the most rugged, environmentally challenging

applications.
