UA741 Pinout and Function Description

 1、UA741  Description:

The UA741 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.The UA741C device is characterized for operation from 0°C to 70°C. The UA741M device(obsolete) is characterized for operation over the full military temperature range of  –55°C to 125°C.

2、UA741  Features:

• Short-Circuit Protection

• Offset-Voltage Null Capability

• Large Common-Mode and Differential Voltage

• Ranges

• No Frequency Compensation Required

• No Latch-Up
