Supporting Information
Overview
The LMR1002F-LB is ROHM’s first zero-drift op amp using the chopper method. In contrast to conventional low-offset op amps featuring a typical input offset voltage of 150µV (Max.), this product limits input offset voltage to just 9µV (94% lower). This eliminates the need for peripheral components or software to adjust the input offset voltage, reducing both design person-hours and costs. On top, input offset voltage temperature drift is just 0.05µV/°C (Max.) in the operating temperature range of -40°C to +125°C - the lowest among ROHM’s op amps. Enabling accurate amplification of measured sensor signals without being affected by environmental changes such as temperature contributes to high accuracy control of industrial equipment in factories. This, coupled with a wide supply voltage range of 2.7V to 5.5V and rail-to-rail input/output, make it ideal for a variety of industrial applications.
