NTE928M Low Power Dual Operational Amplifier PDIP-8
Info als pdf File
To order >>> NTE928SM (8-SOIC)
Description:
Utilizing the circuit designs perfected for recently introduced Quad Operational Amplifiers, the NTE928M/NTE928SM dual operational amplifier features low power drain, a common mode input voltage range extending to ground/V
EE, and Single Supply or Split Supply Operation.
This amplifier has several distinct advantages over standard operational amplifier types in single supply applications. It can operate at supply voltages as low as 3V or as high as 32V with quiescent 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 external biasing power supply voltage.
Features:
- Short Circuit Protected Outputs
- True Differential Input Stage
- Single Supply Operation: 3V to 32V
- Low Input Bias Current
- Internally Compensated
- Common Mode Range Extends to Negative Supply
- 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. |

| Note 4. | The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is VCC-1.7V, but either or both inputs can go to +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. |
