Quadruple Operational Amplifiers

1 Features

• Wide supply range: 3 V to 36 V (B, BA versions)

• Low input offset voltage maximum at 25°C: ±2 mV

(BA versions, LM2902A, LM124A)

• 2-kV ESD protection (HBM) (B, BA, K versions)

• Internal RF and EMI filter (B, BA versions)

• Common-mode input voltage range includes V–

• Input voltage differential can be driven up to supply

voltage

• On products compliant to MIL-PRF-38535, all

parameters are tested unless otherwise noted. On

all other products, production processing does not

necessarily include testing of all parameters.

2 Applications

• Merchant network and server power supply units

• Multi-function printers

• Power supplies and mobile chargers

• Desktop PC and motherboard

• Indoor and outdoor air conditioners

• Washers, dryers, and refrigerators

• AC inverters, string inverters, central inverters, and

voltage frequency drives

• Uninterruptible power supplies

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 cost-

sensitive 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.
