Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Features
• Internall y Freq uency Compensated for Unity Gain
• Large DC Voltage Gain: 100dB
• Wide Po wer 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 th e low power
supply current drain is independent of the magnitude of the
power supply voltage. Applicat ion areas include t ransducer
amplifier , DC gain blocks and all the conventional OP-AMP
circuits which now can be easily implemented in single
power supply systems.
