KA1458 Dual Operational Amplifier

www.fairchildsemi.com KA1458 Dual Operational Amplifier

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