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

Note 1: The maximum junction temperature of the LM747C/LM747E is 100§C. For operating at elevated temperatures, devies in the TO-5 package must be
derated based on a thermal resistance of 150

§

C/W, junction to ambient, or 45§C/W, junction to case. The thermal resistance of the dual-in-line package is 100§C/

W, junction to ambient.
