CA145B, CA1558 (dual types); CA741C, CA741 (single-types); CA747C, CA747 (dual types); CA748C, CA748 (single types) general-purpose, high-gain operational amplifiers military, industrial, commercial applications.
These monolithic silicon integrated-circuit devices provide output short-circuit protection latch-free operation. These types also feature wide common-mode differential-mode signal ranges have low-offset voltage nulling capability when used with appropriately valued potentiometer. 5-megohm potentiometer used offset nulling types CA748C, CA748 (See Fig. 10); 10-kilohm potentiometer used offset nulling types CA741C, CA741, CA747CE, CA747E {See Fig. types CA1458, 558, CA747CT, have specific terminals offset nulling. Each type consists differential-input amplifier that effectively drives gain level-shifting stage having complementary emitter-follower output.
manufacturing process make possible produce operational amplifiers with low-burst ("popcorn") noise characteristics. Type CA6741, low-noise version CA741, gives limit specifications burst noise data bulletin, File 530. Contact your Sales Representative information pertinent other operational amplifier types that meet low-burst noise specifications.
This operational amplifier line also offers circuit designer option operation with internal external phase compensation.
Types CA748C CA748, which externally phase compensated (terminals permit choice operation improved bandwidth slew-rate capabilities. Unity gain with external phase compensation obtained with single 30-pF capacitor. other types internally phase-com pensated.
