NTE987/NTE987SM
Integrated Circuit
Quad, Low Power OP Amp
Description:
The NTE987 and NTE987SM are low cost quad operational amplifiers with true differential inputs.
These have several distinct advantages over standard operational amplifier types in single supply ap-
plications. The quad amplifier 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 components in many applications. The output voltage range also includes the nega-
tive power supply voltage.

Note 1. 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.
