High common mode voltage range and absence of “latch up" make the LM1458 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. Internal frequency compensation Short circuit protecion Large common mode and differential voltage range No latch up Low power consumption 8-DIP 1 8-SOP 1 Internal Block Diagram Rev. 1.0.1 ©2001 Fairchild Semiconductor Corporation LM1458/LM1458C Schematic Diagram Absolute Maximum Ratings Parameter Power Supply Voltage Input Differential Voltage Value Unit VCC ±18 V VI(DIFF) 30 V VI ±15 V Operating Temperature Range TOPR 0 ~ + 70 °C Storage Temperature Range TSTG - 65 ~ + 150 °C Input Voltage 2 Symbol LM1458/LM1458C Electrical Characteristics (VCC = + 15V, VEE = - 15V, TA = 25 °C unless otherwise specified) Parameter Symbol Input Offset Voltage VIO Input Offset Current Input Bias Current Large Signal Voltage Gain Input Voltage Range Input Resistance Conditions RS≤10KΩ LM1458C LM1458 Unit Min.
