LM1458M

www.fairchildsemi.com LM1458/LM1458C 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 LM1458/LM1458C 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 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. 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 Input Voltage Operating Temperature Range 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 LM1458/LM1458C 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 V O = 0V RS≤10KΩ RS≤10KΩ Conditions RS≤10KΩ VO(P-P) = ± 10V, RL≥2.0KΩ LM1458C Min. 20 ± 11 0.3 60 77 ± 11 ± 19 Typ. 2.0 20 80 200 ± 13 1.0 90 90 2.3 ± 14 ± 13 20 70 Max. 10 300 700 8.0 240 Min. 20 ± 12 0.3 70 77 ± 12 ± 10 LM1458 Typ. 2.0 20 80 200 ± 13 1.0 90 90 2.3 ± 14 ± 13 20 70 Max. 6.0 200 500 5.6 170 Unit mV nA nA V/mV V MΩ dB dB mA V mA mW TR OS SR VI = 20mV,RL≥2KΩ,CL≤100pF VI = 20mV,RL≥2KΩ,CL≤100pF VI = 10V,RL≥2KΩ,CL≤100pF - 0.3 15 0.5 - - 0.3 15 0.5 - µs % V/µs 3 LM1458/LM1458C Electrical Characteristics (VCC = + 15V, VEE = - 15V, Note1, unless otherwise specified) Parameter Input Offset Voltage Input Offset Current Input Bias Current Large Signal Voltage Gain Common Mode Rejection Ratio Power Supply Rejection Ratio Output Voltage Swing Input Voltage Range Symbol VIO IIO IBIAS GV CMRR PSRR VO(P.P) VI(R) Conditions RS≤10KΩ VO(P-P)= ± 10V, RL≤2.0KΩ RS≥10KΩ RS≥10KΩ RL = 10KΩ RL = 2KΩ LM1458C Min. 15 70 77 ± 11 ±9 ± 12 Typ. 90 90 ± 14 ± 13 Max. 12 400 1000 Min. 15 70 77 ± 12 ± 10 ± 12 LM1458 Typ. 90 90 ± 14 ± 13 Max. 7.5 300 800 V Unit mV nA nA V/mV dB dB V Note : 1.
