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.
