UA747CN Datasheet

Operational Amplifiers - Op Amps


The UA747CN is a dual general-purpose operationalamplifier featuring offset-voltage null capability.Each half is electrically similar to uA741.The high common-mode input voltage range andthe absence of latch-up make this amplifier idealfor voltage-follower applications. The device isshort-circuit protected and the internal frequencycompensation ensures stability without externalcomponents. A low-value potentiometer may beconnected between the offset null inputs to null outthe offset voltage as shown in Figure 2.The uA747C is characterized for operation from0°C to 70°C; the uA747M is characterized foroperation over the full military temperature rangeof −55°C to 125°C. UA747CN Features • No Frequency Compensation Required• Low Power Consumption• Short-Circuit Protection• Offset-Voltage Null Capability• Wide Common-Mode and DifferentialVoltage Ranges• No Latch-Up• Designed to Be Interchangeable WithFairchild μA747C and μA747M
