Description:

The NTE7144 is an integrated circuit operational amplifier in an 8–Lead Mini–DIP type package that combines the advantages of high–voltage PMOS transistors with high–voltage bipolar transistors on a single monolithic chip. This device features gate–protected MOSFET (PMOS) transistors in the input circuit to provide very–high–input impedance, very–low–input current, and high–speed performance. The NTE7144 operates at supply voltages from 4V to 36V (either single or dual supply) and is internally phase–compensated to achieve stable operation in unity–gain follower operation.
