UA747 (ACTIVE) Dual General-Purpose Operational Amplifier

Dual General-Purpose Operational Amplifier - UA747
Datasheet
 

Description

The uA747 is a dual general-purpose operational amplifier featuring offset-voltage null capability. Each half is electrically similar to uA741.

The high common-mode input voltage range and the absence of latch-up make this 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 Figure 2.

The uA747C is characterized for operation from 0°C to 70°C; the uA747M is characterized for operation over the full military temperature range of -55°C to 125°C.

Features

  • No Frequency Compensation Required
  • Low Power Consumption
  • Short-Circuit Protection
  • Offset-Voltage Null Capability
  • Wide Common-Mode and Differential Voltage Ranges
  • No Latch-Up
  • Designed to Be Interchangeable With Fairchild uA747C and uA747M
