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 (600 µV, typical), common-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 3 mV (2 mV maximum for LM324BA and LM2902BA) and quiescent current of 240 µA per amplifier (typical). High ESD (2 kV HBM and 1.5 kV 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.

 

LM324B와 LM2902B는 업계 표준 연산 증폭기(Operational Amplifier)인 LM324와 LM2902의 차세대 버전으로, 4개의 고전압(36V) 연산 증폭기를 포함하고 있습니다. 이 제품들은 비용 민감형 애플리케이션에서 높은 가치를 제공하며, 낮은 오프셋 전압(600µV, 일반값), 접지까지 확장되는 공통 모드 입력 범위, 그리고 높은 차동 입력 전압 처리 능력 등의 특징을 갖추고 있습니다.

LM324B와 LM2902B는 단일 이득(unity-gain)에서 안정적이며, 최대 오프셋 전압이 3mV (LM324BA와 LM2902BA는 최대 2mV), 앰프당 정지 전류는 240µA(일반값)에 도달합니다. 높은 ESD 보호(2kV HBM 및 1.5kV CDM)와 통합된 EMI 및 RF 필터가 탑재되어 있어, LM324B와 LM2902B는 환경적으로 까다롭고 내구성이 요구되는 애플리케이션에 사용될 수 있습니다. 

또한 LM324B와 LM2902B는 LM224, LM324, LM2902 모든 버전과 호환되며, 대체품으로 사용 가능합니다.
