■ 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.

Explanation
Input Offset Voltage Drift
Input Offset Voltage Drift = ∆VIO / ∆T
∆T : Amount of Temperature Change.
∆VIO : Amount of Input Offset Voltage.
Common Mode Input Voltage range A range of input voltage at which the operational amplifier can function.
Common Mode Rejection Ratio
CMR = 20log | ( ∆VCM / ∆VIO )|
∆VCM : Amount of Input Voltage.
∆VIO : Amount of Input Offset Voltage.
Supply Voltage Rejection Ratio SVR = 20log |( ∆VS / ∆VIO )|
∆VS : Amount of Supply Voltage.
∆VIO : Amount of Input Offset Voltage.
Common Mode Input Impedance RIC = ∆VCM / ∆IB
∆VCM : Amount of Input Voltage.
∆IB : Amount of Input Bias Current.
Voltage Gain
AV = 20log |( ∆VO / ∆VＩＯ )|
∆VO : Amount of Output Voltage.
∆VＩＯ : Amount of Input Offset Voltage.
