Zero-Drift Operational Amplifier IC Exhibits Resilience to Thermal Fluctuations

11 February 2024

The chopper-based LMR1002F-LB single-channel operational amplifier IC from ROHM has an offset voltage to just 9µV and its temperature drift is only 0.05µV/°C (so the effects of changes in environmental conditions are mitigated).

This device’s supply voltage range goes from 2.7V to 5.5V, and there is a typical input bias current 0.15nA. An operational temperature range spanning from -40°C through to +125°C is supported. It is optimised for use current sensing applications in both industrial and automotive settings - such as in power control inverters, pressure detection equipment, etc.
