0.9MHz单路和双路，军事，工业和商业应用的高增益运算放大器 0.9MHz Single and Dual, High Gain Operational Amplifiers for Military, Industrial and Commercial Applications
The CA1458, CA1558 dual types; C, 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 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.
