CA741, CA741C, CA1458, CA1558,

LM741, LM741C, LM1458

0.9MHz Single and Dual, High Gain

Operational Amplifiers for Military,

Industrial and Commercial Applications

The CA1458, CA1558 (dual types); CA741C, CA741 (single

types); high-gain operational amplifiers for use in military,

industrial, and commercial applications.

These monolithic silicon integrated circuit devices provide

output short circuit protection and latch-free operation.

These types also feature wide common mode and

differential mode signal ranges and have low offset voltage

nulling capability when used with an appropriately valued

potentiometer. A 10k

Ω potentiometer is used for offset

nulling types CA741C, CA741 (see Figure 1). Types

CA1458, CA1558 have no specific terminals for offset

nulling. Each type consists of a differential input amplifier

that effectively drives a gain and level shifting stage having

a complementary emitter follower output.

The manufacturing process make it possible to produce IC

operational amplifiers with low burst “popcorn’’ noise

characteristics.

Technical Data on LM Branded types is identical to the

corresponding CA Branded types.
