General-Purpose Operational Amplifier - UA741

UA741 (ACTIVE)

General-Purpose Operational Amplifier

 

Description

The µA741 device is a general-purpose operational amplifier featuring offset-voltage null capability.

The high common-mode input voltage range and the absence of latch-up make the amplifier ideal for voltage-follower applications. The device is short-circuit protected and the internal frequency compensation ensures stability without external components. A low value potentiometer may be connected between the offset null inputs to null out the offset voltage as shown in .

The µA741C device is characterized for operation from 0°C to 70°C. The µA741M device (obsolete) is characterized for operation over the full military temperature range of –55°C to 125°C.

Features

  • Short-Circuit Protection
  • Offset-Voltage Null Capability
