Integrated Circuit
Low Power Dual Operational Amplifier
Description:
Utilizing the circuit designs perfected for recently introduced Quad Operational Amplifiers, the
NTE928 dual operational amplifier features low power drain, a common mode input voltage range
extending to ground/VEE, and Single Supply or Split Supply Operation.
This amplifier has several distinct advantages over standard operational amplifier types in single sup-
ply applications. It can operate at supply voltages as low as 3.0 Volts or as high as 32 Volts with quies-
cent currents about one–fifth of those associated with the NTE941 (on a per amplifier basis). The
common mode input range includes the negative supply, thereby eliminating the necessity for exter-
nal biasing power supply voltage.

D Short Circuit Protected Outputs
D True Differential Input Stage
D Single Supply Operation: 3.0 to 32 Volts
D Low Input Bias Currents

D Common Mode Range Extends to Negative Supply

Note 1. Split Power Supplies
Note 2. For supply voltages less than 32V, the absolute maximum input voltage is equal to the supply
voltage.
Note 3. This input current will only exist when the voltage is negative at any of the input leads. Normal
output states will reestablish when the input voltage returns to a voltage greater than 0.3V.

Note 4. The input commonmode voltage or either input signal voltage should not be allowed to go
negative by more than 0.3V. The upper end of the commonmode voltage range is
VCC1.7V, but either or both inputs can goto +32V without damage.
Note 5. Short circuit from the output to VCC can cause excessive heating and eventual destruction.
Destructive dissipation can result from simultaneous shorts on all amplifiers.
