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 extending to ground/VEE 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 3.0 volts or as high as 32 volts 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.

Prices on some items may differ from those advertised in RadioShack stores. All merchandise may not be available at all stores, and all stores may not participate in all sales promotions. We recommend you contact the store to confirm product availability and price.
* Split power supplies ** For supply voltages less than 32V, the absolute maximum input voltage is equal to the supply voltage. *** 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.
