NTE7144 Integrated Circuit BIMOS Operational Amplifier w/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 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. 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 damage from load-terminal short-circuiting to either supply-rail or to GND.
