‘Zero-drift’ op-amp has 9µV, 0.05µV/°C input offset

Rohm is aiming at industrial and consumer applications with a ‘zero-drift’ operational amplifier which scores 9µV and 50nV/°C for its input offset – both maximum figures, which are typically 1µV and 15nV/°C.

Rohm LMR1002F-LB zero drift op amp

A first for the company, LMR1002F-LB, as it will be called, has a chopper architecture.

Input current is typically 150pA (25°C) with 10pA offset. Both inputs and output are rail-to-rail.


Gain-bandwidth product is 1.5MHz and slew-rate is 1.3V/μs (measured at different gains, see data sheet).


It works over 2.7 to 5.5V and -40°C to +125°C, and comes in a 5 x 6.20mm SOP8 package.
