Integrated Circuit
Operational Amplifier
Description:
The NTE903 is an operational amplifier in a 12–Lead TO5 type metal can having all the desirable fea-
tures and chatacteristics of its prototypes plus a lower noise figure and improved characteristics for
offset voltage, offset current, bias current, and impedance.
Typical Applications:
D Narrow–Band and Band–Pass Amplifier
D Operational Functions
D Feedback Amplifier
D DC and Video Amplifier
D Multivibrator
D Oscillator
D Comparator
D Servo Driver
D Scaling Adder
D Balanced Modulator–Driver
