NTE930 Linear Integrated Circuit BiMOS Operational Amp
Description: The NTE930 is an integrated circuit operational amplifier in an 8-Lead Metal Can type package that combines the advantages of both COS/MOS and bipolar transistors on a monolithic chip. Gate-protected P-channel MOS/FET (PMOS) transistors are used in the input circuit to provide very-high-input impedance, very-low-input current and exceptional speed performance. 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 in single-supply applications. A complementary-symmetry MOS (COS/MOS) transistor pair, capable of swinging the output voltage to within 10mV of either supply-voltage terminal (at very high values of load impedance), is employed as the output circuit. The NTE930 operates at supply voltages ranging from 5 to 16 volts, or 2.5 to 8 volts when using split supplies. They can be phase compensated with a single external capacitor, and have terminals for adjustment of offset voltage for applications requiring offset-null capability. Terminal provision are also made to permit strobing of the output stage.
