Description
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.
