Dual Operational Amplifier - LM747

LM747 (ACTIVE)

Dual Operational Amplifier

 

Recommended alternative parts

  • LM8272  -  Wider Bandwidth,RRIO,unlimited Output Cap Load
  • LMC6061  -  Lower Offset Voltage

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 +70°Cinstead of -55°C to +125°C.

Features

  • No frequency compensation required
  • Short-circuit protection
  • Wide common-mode and differential voltage ranges
  • Low power consumption
  • No latch-up
  • Balanced offset null
