KA324/KA324A, KA2902
Quad Operational Amplifier
Features
Description
• Internally Frequency Compensated for Unity Gain
• Large DC Voltage Gain: 100dB
• Wide Power Supply Range:
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
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.
