OPA4277UA/2K5G4 Application Field and Working Principle

The OPA4277UA/2K5G4 is a dual, monolithic JFET operational amplifier with high voltage, low noise, and low distortion. It is designed for applications such as low-voltage instrumentation, signal conditioning, or audio signal-processing. The OPA4277UA/2K5G4 operates from +2.7V to +36V power supplies and features a wide bandwidth (2.2GHz) and a very low noise figure of 5RuinpF.

The OPA4277UA/2K5G4 utilizes complementary JFET technology to provide high open-loop gain, low input bias current, low power and very low distortion. The unity gain stable design has internal protection and electrostatic protection on the input and output pins.

Working Principle

The OPA4277UA/2K5G4 works based on the differential amplifier circuit. It uses a pair of input transistors connected as a differential amplifier. Two input transistors, Q1 and Q2, have their bases connected together and their collectors connected to two outputs. The output is taken by the differential amplifier from the difference between the two input voltages.

The differential amplifier is connected to a common-mode feedback loop. This loop is used to adjust the gain of the differential amplifier to a predetermined level. The output of the differential amplifier is then connected to an operational amplifier.

The OPA4277UA/2K5G4 has a voltage-controlled input and a low power supply voltage. This allows the amplifier to work with signals from low-voltage sources such as instrumentation. Additionally, the OPA4277UA/2K5G4 has a low input offset voltage and a high common-mode rejection ratio (CMV).
