Fairchild Semiconductor KA1458 Datasheet
KA1458
Dual Operational Amplifier

Features
• Internal frequency compensation
• Short circuit protecion
• Large common mode and differential voltage range
• No latch up
• Low power consumption
Description
The KA1458 series are dual general purpose operational
amplifiers, having short circuits protected and require no
external components for frequency compensation. High
common mode voltage range and absence of “latch up"
make the KA1458 ideal for use as voltage followers. The
high gain and wide range of operating voltage provides
superior performance in integra tor, summing amplifier and
general feedback applications.
