OPA602APG4 is Texas Instruments’ newest operational amplifier (Op Amp) market. It is a two-stage amplifier designed for voltage-in, current-out applications such as thermocouples, RTDs, and other bridge sensors. It is one of the optimal solutions when high accuracy and precision are needed in process industries.

Application Field

• Industrial equipment
• Thermocouple systems
• Measurement and sensing systems
• Process control systems

Working Principle

The OPA602APG4 consists of two stages: an input stage (Op Amp) for noise cancellation and an output stage for precision current. The input stage is an advanced audio amplifier, which significantly reduces the noise of the measurement system by canceling out common-mode and normal-mode noise. The second stage is a fully differential amplifier, specially designed for low-power and precision current output. It allows the user to choose between a buffered output or a non-buffered output.

The output stage also features a fully differential input stage, which ensures low-power drain, adjustable gain, and ensures the high-performance operation of the amplifier. The output stage enables the user to select the output current range by changing the voltage references. The adjustable gain of the output stage is also useful in calibration of the system.

The OPA602APG4 is designed to be highly configurable and supports an array of functions and features that make it ideal for industrial application. The amplifier is offered in a small SOT-23 package and can easily be integrated in systems.
