MAX400	This product is No Longer Available.	This product was manufactured for Maxim by an outside wafer foundry using a process that is no longer available. It is not recommended for new designs. For further information, contact us. The data sheet remains available for existing users. To the best of our knowledge, a second-source replacement for this part is available from Analog Devices.

Description

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.
