BIMOS Operational Amplifier

/MOSFET Input, Bipolar Output
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 in-
put circuit to provide very–high–input impedance, very–low–input current, and high–speed perfor-
mance. 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.
The use of PMOS field–effect transistors in the input stage results in common–mode input–voltage
capability down to 0.5V below the negative–supply terminal, an important attribute for single–supply
applications. The output stage uses bipolar transistors and includes built–in protection against dam-
age from load–terminal short–circuiting to either supply–rail or to GND.
