1 KA258/KA258A, KA358/KA358A, KA2904 Dual Operational Amplifier Features Internally Frequency Compensated for Unity Gain Large DC 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 Range Includes Ground Large Output Swing: 0V DC to - 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. 8-DIP 8-SOP 1 9-SIP 1 1 Internal Block Diagram OUT1 1 8 VCC IN1 (-) 2-7 OUT IN1 (+) IN2 (-) GND IN2 (+) VCC OUT1 IN1(-) IN1(+) GND IN2(+) IN2(-) OUT2 VCC Rev Fairchild Semiconductor Corporation
