LM2902K Datasheet | Texas Instruments

Features - New LM324B and LM2902B - B versions are drop-in replacements for all versions of LM224, LM324, and LM2902 - Improved specifications of B version - Supply range: 3V to 36V (B, BA versions) - Low input offset voltage: ±2m V (BA version) / 3m V (B version) - ESD rating: 2k V (HBM), 1.5k V (CDM) - EMI rejection: integrated RF and EMI filter - Low input bias current: 50n A maximum (across - 40°C to 125°C) - mon-mode input voltage range includes V- - Input voltage differential can be driven up to supply voltage - For dual B versions, see LM358B and LM2904B 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 (36V) op amps. These devices provide outstanding value for cost-sensitive applications, with features including low offset (600µV, typical), mon-mode input range to ground, and high differential input voltage capability. The LM324B and LM2902B are unity-gain stable and achieve a low offset voltage maximum of 3m V (2m V maximum for LM324BA and LM2902BA) and quiescent current of 240µA per amplifier (typical). High ESD (2k V HBM and 1.5k V CDM) and integrated EMI and RF filters enable the LM324B and LM2902B devices to be used in the most rugged, environmentally challenging applications. The LM324B and LM2902B can drop-in replace all versions of the LM224, LM324, and LM2902 devices.
