| www.fairchildsemi.com 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 integrator, summing amplifier and general feedback applications. 8-DIP 1 8-SOP 1 9-SIP 1 Internal Block Diagram Rev. 1.0.1 (c)2001 Fairchild Semiconductor Corporation KA1458 Schematic Diagram Absolute Maximum Ratings Parameter Power Supply Voltage Input Differential Voltage Input Voltage Operating Temperature Range KA1458 Storage Temperature Range Symbol VCC VI(DIFF) VI TOPR TSTG Value 18 30 15 0 ~ + 70 - 65 ~ + 150 Unit V V V C C 2 KA1458 Electrical Characteristics (VCC = + 15V, VEE = - 15V, TA = 25 C unless otherwise specified) Parameter Input Offset Voltage Input Offset Current Input Bias Current Large Signal Voltage Gain Input Voltage Range Input Resistance Common Mode Rejection Ratio Power Supply Rejection Ratio Supply Current (Both Amplifier) Output Voltage Swing Output Short Circuit Current Power Consumption Transient Response (Unity Gain) Rise Time Overshoot Slew Rate Symbol VIO IIO IBIAS GV VI(R) RI CMRR PSRR ICC VO(PP) ISC PC VO = 0V RS10K RS2K Conditions RS10K VO(P-P) = 10V, RL2.0K KA1458 Min.
