NTE7144
Integrated Circuit
BIMOS Operational Amplifier
w/MOSFET Input, Bipolar Output
Description:
The NTE7144 is an integrated circuit operational amplifier in an 8âLead MiniâDIP type package that
combines the advantages of highâvoltage PMOS transistors with highâvoltage bipolar transistors on
a single monolithic chip. This device features gateâprotected MOSFET (PMOS) transistors in the in-
put circuit to provide veryâhighâinput impedance, veryâlowâinput current, and highâspeed perfor-
mance. The NTE7144 operates at supply voltages from 4V to 36V (either single or dual supply) and
is internally phaseâcompensated to achieve stable operation in unityâgain follower operation.
The use of PMOS fieldâeffect transistors in the input stage results in commonâmode inputâvoltage
capability down to 0.5V below the negativeâsupply terminal, an important attribute for singleâsupply
applications. The output stage uses bipolar transistors and includes builtâin protection against dam-
age from loadâterminal shortâcircuiting to either supplyârail or to GND.
