Application of OPA2614IDG4

The OPA2614IDG4 is used in a variety of applications such as medical diagnostic/measurement equipment, robotics, drive and motion control, commercial/industrial automation, and control systems. Its low voltage noise, current consumption, and wide bandwidth make it ideal for these types of applications.The OPA2614IDG4 can be used for current sensing operations, signal conditioning, instrumentation amplifiers, filters, drivers for motors and actuators, low noise signal amplification, and low-power buffering. It can also be used to measure signal voltage levels or to invert or translate signals by adjusting the gain.

Working Principle of OPA2614IDG4

The OPA2614IDG4 is an inverting operational amplifier (op amp) with a gain of $\frac{V_{out}}{V_{in}}=-A$ where A is the gain set by the external resistor. The gain is given by$$A=\frac{R_{f}}{R_{in}} $$where Rf is the feedback resistor and Rin is the input resistor. The op amp has two inputs: the positive input and the negative input. The voltage at the positive input is applied to the inverting input of the op amp and the voltage at the negative input is applied to the non-inverting input. The difference between the two signals is amplified by the gain, A. The output voltage is given by$$V_{out} = -A*(V_{in+}-V_{in-}) $$In the OPA2614IDG4, the positive input is typically used for the signal voltage and the negative input is connected to ground. The gain of the OPA2614IDG4 is usually set to unity such that$$V_{out}=-(V_{in+}-V_{GND}) $$This arrangement allows the OPA2614IDG4 to amplify the voltage signal while rejecting the effects of any DC input common-mode noise. In addition, the high input impedance of the OPA2614IDG4 ensures that the signal source is not load down.

Conclusion

The OPA2614IDG4 is an ideal op amp for applications such as medical diagnostic/measurement equipment, robotics, drive and motion control systems, commercial/industrial automation systems and control systems. It has low voltage noise, low supply current, and high input impedance which makes it ideal for applications requiring precision and low noise performance. The OPA2614IDG4 is an inverting operational amplifier with an adjustable gain of up to 1000V/V. Its working principle is based on the differential input voltage being amplified by a gain set by the external resistor.
