KA258/KA258A, KA358/KA358A,
KA2904
Dual Operational Amplifier
Features
• Internally Frequency Compensated for Unity Gain
• Large DC Voltage Gain: 100dB
• Wide Power Supply Range:
KA258/KA258A, KA358/KA358A: 3V ~ 32V (or
±1.5V~ 16V)
KA2904 : 3V~26V (or ±1.5V ~ 13V)
• Input Common Mode Voltage Range Includes Ground
• Large Output Voltage Swing: 0V DC to Vcc - 1.5V DC
• Power Drain Suitable for Battery Operation.
Description
The KA258 series consist of two independent, high gain,
internally frequency compensated operational amplifiers
which were designed specifically to operate from a single
power supply over a wide range of voltage. Operation from
split power supplies is also possible and the low power
supply current drain is independent of the magnitude of the
power supply voltage. 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.
