KA224/KA224A, KA324/KA324A, KA2902

Quad Operational Amplifier

Features	Description
• Internally Frequency Compensated for Unity Gain	The KA324 series consist of four independent, high gain,
• Large DC Voltage Gain: 100dB	internally frequency compensated		operational amplifiers
• Wide Power Supply Range:	which were designed specifically to		operate from a single
KA224 / KA224A, KA324 / KA324A : 3V~32V (or ± 1.5	power supply over a wide	voltage range. Operation from
~ 16V)	split power supplies is also possible so long as the
KA2902: 3V~26V (or ± 1.5V ~ 13V)	difference between the two supplies is 3 volts to 32 volts.
• Input Common Mode Voltage Range Includes Ground	Application areas include	transducer amplifier, DC gain
• Large Output Voltage Swing: 0V to VCC -1.5V	blocks and all the conventional OP Amp circuits which now
• Power Drain Suitable for Battery Operation	can be easily implemented in single power supply systems.
