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 vo l tage. Applicatio n a reas inc lud e tr ans d uce r
amplifier, DC gain blocks and all the conventional OP-AMP
circuits which now can be easily implemented in single
power supply systems.
