• Large Output Voltage Swing: 0V to V

• Power Drain Suitable for Battery Operation

CC

-1.5V

Description

The KA324 serie s 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.
