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 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.Features
