KA3303/KA3403
Quad Operational Amplifier
Features
•Output voltage can swing to GND or negative supply
•Wide power supply range;
•Single supply of 3.0V to 36V
•Dual supply of ± 1.5V to ± 18V
•Electrical characteristics similar to the KA741
•Class AB output stage for minimal crossover distortion
•Short circuit protected output.
Description
The KA3303 series is a monolithic Quad operational amplifier consisting of four independent amplifiers. The device has high gain, internally frequency, compensated operational amplifiers designed to operate from a single power supply or dual power supplies over a wide range of voltages. The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications.
