CA741, CA741C, CA1458, CA1558,

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 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.
