ROHM's LMR1002F-LB for Accurate Signal Amplification in Industrial and Consumer Electronics

LMR1002F-LB - Zero-drift Operational Amplifier
LMR1002F-LB - Zero-drift Operational Amplifier

ROHM introduces the LMR1002F-LB, a zero-drift operational amplifier designed for industrial and consumer electronics applications. This op amp aims to minimize input offset voltage and its temperature drift, crucial for accurately amplifying output signals from sensors in various measurement devices. In response, ROHM developed the LMR1002F-LB, leveraging proprietary analog circuit technology. 

Unlike conventional op amps with higher input offset voltages, this model significantly reduces offset voltage to just 9µV (94% lower), minimizing the need for additional adjustments or peripheral components. Its low input offset voltage temperature drift of 0.05µV/°C ensures stable performance across a wide temperature range (-40°C to +125°C), contributing to high accuracy control of industrial equipment. With features like a wide supply voltage range of 2.7V to 5.5V and rail-to-rail input/output, it caters to various industrial applications, enhancing performance without promotional language.
