FEATURES
The NJMOP177 is a 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
are100% tested and specified from
−40
to 85ºC.
The NJMOP177 is suitable for high gain circuit amplified small signal and sets required stable behavior
over a wide temperature range.
