Description
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 complementar y emitter follower output.
The manufacturing process make it possible to produce IC
operational amplifiers with low burst “popcorn’’ noise
characteristics. The CA741 giv es limit specifications f or b urst
noise in the data bulletin, File Number 530. Contact your
Sales Representative for information pertinent to other oper-
ational amplifier types that meet low burst noise
specifications.
Technical Data on LM Branded types is identical to the corre-
sponding CA Branded types.
