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 10kΩpotentiometer 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.
