ROHM unveils LMR1002F-LB: Zero-drift Op Amp both industrial and consumer grade
Date: 07/02/2024
ROHM introduces the LMR1002F-LB, a zero-drift operational amplifier (op amp) designed both for industrial and consumer electronics applications. Designed to minimize input offset voltage and temperature drift, this new op amp accurately amplifies output signals from sensors in various measurement devices. With a focus on current sensing applications like power control inverters and environmental detectors, the LMR1002F-LB promises precision and reliability in demanding scenarios.
As industries demand ever more precise control over applications, the need for accurate environmental sensing becomes paramount. ROHM addresses this challenge with the LMR1002F-LB, designed to mitigate voltage errors caused by input offset voltage and temperature drift. Leveraging proprietary analog circuit technology, this op amp employs the chopper method, ensuring input offset voltage is limited to a mere 9µV – a 94% reduction compared to conventional low-offset op amps eliminating the need for additional peripheral components or software adjustments, streamlining design efforts and reducing costs.
LMR1002F-LB also feature a minimal input offset voltage temperature drift of just 0.05µV/°C, ensuring consistent performance across a wide temperature range (-40°C to +125°C). This stability enables precise amplification of sensor signals, unaffected by environmental fluctuations, thereby enhancing the accuracy of industrial equipment control in factory settings. With a versatile supply voltage range of 2.7V to 5.5V and rail-to-rail input/output capability, this op amp caters to a diverse range of industrial applications, promising reliability and efficiency.
ROHM's LMR1002F-LB represents a significant advancement in op amp technology, addressing the pressing need for precision and reliability in industrial and consumer electronics. By minimizing input offset voltage and temperature drift, this zero-drift op amp ensures accurate signal amplification, crucial for applications ranging from power control inverters to environmental detectors. Moving forward, ROHM remains committed to enhancing op amp performance, reducing noise, and expanding power supply voltage ranges, with the ultimate goal of contributing to solutions for societal challenges through improved application control accuracy.
