NTE996
Linear Integrated Circuit
Operational Transconductance Amplifier
Description:
The NTE996 is a programmable transconductance block intended to fulfill a wide variety of variable
gain applications. This device has differential inputs and high impedance push–pull outputs. The
NTE996 has high input impedance and its transconductance (g
fier bias current (I
ABC
).
High slew rate together with programmable gain make the NTE996 an ideal choice for variable gain
applications such as sample and hold, multiplexing, filtering, and multiplying,
