KA224/KA224A, KA324/KA324A, KA2902
Quad Operational Amplifier
Features
Internally Frequency Compensated for Unity Gain Large DC Voltage Gain: 100dB Wide Power Supply Range: KA224 / KA224A, KA324 / KA324A : 3V 32V (or 1.5 16V) KA2902: 3V 26V (or 1.5V 13V) Input Common Mode Voltage Range Includes Ground Large Output Voltage Swing: 0V to VCC -1.5V Power Drain Suitable for Battery Operation

Description
The KA324 series consist of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide voltage range. Operation from split power supplies is also possible so long as the difference between the two supplies is 3 volts to 32 volts. Application areas include transducer amplifier, DC gain blocks and all the conventional OP Amp circuits which now can be easily implemented in single power supply systems.
