GENERAL DESCRIPTION
The NJMOP177/NJMOP1772 are high precision operational amplifier
features very low offset voltage and drift.
It also achieves high common mode rejection, low noise and high open
loop gain. DC characteristics are 100% tested and specified from
−40
to
85ºC.
The NJMOP177/NJMOP1772 are suitable for high gain circuit amplified
small signal and sets required stable behavior over a wide temperature
range.
