Uploaded by 658056

High-gain single and dual operational amplifiers CA741, CA1458, and CA1558 are specified for military, industrial, and commercial applications. Monolithic silicon integrated circuits provide output short-circuit protection and latch-free operation, with wide common-mode and differential-mode signal ranges. Low-offset design supports differential input drive, gain/level shifting, and complementary emitter follower outputs, including offset nulling for selected variants. Electrical and absolute maximum ratings cover supply voltage, input/output limits, operating temperatures, and electrical characteristics for equipment design guidance.

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 10kΩ potentiometer is used for offset nulling types CA741C, CA741 (See Figure 4); and 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. The CA741 gives limit speciﬁcations for burst noise in the data bulletin, File Number 530. Contact your Sales Representative for information pertinent to other operational ampliﬁer types that meet low burst noisespeciﬁcations. | | | | --- | --- | --- | --- | --- | --- | | Pinouts | | | | | | | CA741, CA741C (TO-5 CAN)

FAQs

What main features do the CA741/CA1458/CA1558 operational amplifiers provide?

They are high-gain monolithic operational amplifiers with output short-circuit protection and latch-free operation. They also offer wide common-mode and differential-mode signal ranges and support low offset behavior with appropriate offset nulling for certain types.

What are the operating temperature ranges listed for different variants?

CA741 and CA1558 are specified from -55°C to +125°C, while CA741C and CA1458 are specified from 0°C to +70°C. The note also states that types can be operated across -55°C to +125°C in any package style, subject to published limits for certain specifications.

What does the document specify about absolute maximum ratings and caution?

It warns that stresses above the listed absolute maximum ratings may cause permanent damage, and that operation above operational section conditions is not implied. It also cautions that the devices are sensitive to electrostatic discharge and users should follow proper I.C. handling procedures.
