Integrated Circuit  
Operational Amp  
Description:  
The NTE945 is a precision, high input impedance operational amplifier in an 8Lead Metal Can type  
package designed for applications requiring extremely low input current errors. This device uses su-  
pergain transistors in a Darlington input stage to get input bias currents that are equal to highquality  
FET amplifierseven in limited temperature range operation.  
Unlike most other internally compensated amplifiers, the MOS compensation capacitor is protected  
to prevent catastrophic failure from overvoltage spikes on the supplies.  
The low current error of this amplifier makes possible many designs that were previously impractical  
with monolithic amplifiers. It will operate from 100msource resistances, introducing less error than  
general purpose amplifiers with 10ksources, Integrators with worst case drifts less than 10µV/sec  
and analog time delays in excess of one day can also be made using capacitors no larger than 1µF.  
Features:  
D Guaranteed Bias Currents as Low as 50pA  
D Maximum Offset Currents Down to 15pA  
D Operates from Supplies of ±3V to ±20V  
D Supply Current Only 300µA at ±20V

Note 1. The maximum junction temperature is +70°C. For operating at elevated temperatures, the  
NTE945 must be derated based on a thermal resistance of +150°C/W, junctiontoambient,  
or +45°C/W, junctiontocase.  
Note 2. The inputs are shunted with backtoback diodes for overvoltage protection. Therefore, ex-  
cessive current will flow if a differential input voltage in excess of 1V is applied between the  
inputs unless some limiting resistance is used.  
Note 3. For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply  
voltage.
