Description
• Low V
IO
The CA3193A and CA3193 are ultra-stable, precision
instrumentation, operational amplifiers that employ both
PMOS and bipolar transistors on a single monolithic chip.
The CA3193A and CA3193 amplifiers are internally phase
compensated and provide a gain bandwidth product of
1.2MHz. They are pin compatible with the industry 741
series and many other IC op amps, and may be used as
replacements for 741 series types in most applications.

The CA3193A and CA3193 can also be used as functional
replacements for op amp types 725, 108A, OP-5, OP-7,
LM11 and LM714 in many applications where nulling is not
employed. Because of their low offset voltage and low offset
voltage vs temperature coefficient the CA3193A and
CA3193 amplifiers have a wider range of applications than
most op amps and are particularly well suited for use as
thermocouple amplifiers, high gain filters, buffer, strain
gauge bridge amplifiers and precision voltage references.

The two types in the CA3193 series are functionally
identical. The CA3193A and CA3193 operate from supply
voltages of ±3.5V to ±18V.
