Dual Operational Amplifier

LM747 Dual Operational Amplifier

November 1994

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
instead of
