| LM747 Dual Operational Amplifier November 1994 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 to a 70 C instead of b55 C to a 125 C Features Y Y Y Y Y Y No frequency compensation required Short-circuit protection Wide common-mode and differential voltage ranges Low power consumption No latch-up Balanced offset null Connection Diagrams Metal Can Package Dual-In-Line Package TL H 11479 -
