Ultra-Low Offset Voltage Operational Amplifier

Please check latest availability status for a specific part variant.


The MAX400 guaranteed maximum 10µV offset error is the lowest input offset voltage of any commercially available (nonchopper) monolithic amplifier. The MAX400 represents a 2.5 times improvement over the highest grade OP07 (the OP07A), and a 5 times improvement over the best commercial temperature range device (OP07E). The offset voltage drift is guaranteed to be a maximum of 0.3µV/°C which is also an improvement over the OP07 family.

For the ultimate in DC performance (5µV maximum offset voltage and 0.05µV/°C maximum offset voltage drift) the MAX420 and MAX430 series of ±15V monolithic, chopper-stabilized amplifiers should be consulted.
