OPA111 is a differential amplifier with high precision, low noise (maximum noise 8nV∥, 10kHz), low drift (maximum temperature drift
1 rjLv/oc), and high common mode rejection ratio (lOOdB). The maximum input bias current is lpA, the minimum open-loop gain is
L20dB, the differential input impedance is 10130, and the common mode input impedance is l014n. The pin functions of OPA 111 are as shown in the figure
