Low Power Dual Operational Amplifier

Description:

Utilizing the circuit designs perfected for recently introduced Quad Operational Amplifiers, the

NTE928S dual operational amplifier features low power drain, a common mode input voltage range

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.

Features:

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 Internally compensated

D Common Mode Range Extends to Negative Supply

D Single and Split Supply Operation

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.
