1 LM747 Dual Operational Amplifier General Description The LM747 is a general purpose dual operational amplifier The two amplifiers share a common bias network and power supply leads Otherwise their operation is completely independent Additional features of the LM747 are no latch-up when input common mode range is exceeded freedom from oscillations and package flexibility The LM747C LM747E is identical to the LM747 LM747A except that the LM747C LM747E has its specifications guaranteed over the temperature range from 0 C toa70 C instead of b55 C toa125 C Features November 1994 No frequency compensation required Short-circuit protection Wide common-mode and differential voltage ranges Low power consumption No latch-up Balanced offset null LM747 Dual Operational Amplifier Connection Diagrams Metal Can Package Dual-In-Line Package Order Number LM747H See NS Package Number H10C V a A and V a B are internally connected TL H Order Number LM747CN or LM747EN See NS Package Number N14A TL H C1995 National Semiconductor Corporation TL H RRD-B30M115 Printed in U S A
