Operational Amplifier as V-I & I-V Convertor

The Operational Amplifier as V-I & I-V Converter from Glass Agencies under the EROSE brand is a specialized laboratory apparatus designed to demonstrate the practical applications of operational amplifiers in voltage-to-current and current-to-voltage conversion. This educational instrument provides students, trainees, and researchers with hands-on experience in understanding signal conversion techniques essential in analog electronics, instrumentation, and sensor interfacing. The apparatus consists of a carefully assembled circuit with operational amplifiers, precision resistors, and clearly labeled input and output terminals, allowing users to connect and analyze both V-I and I-V converter configurations efficiently. In the voltage-to-current (V-I) conversion mode, the operational amplifier produces an output current proportional to the applied input voltage, enabling learners to study controlled current sourcing applications, load driving, and signal conditioning for sensors and transducers. In the current-to-voltage (I-V) conversion mode, the op-amp transforms an input current into a proportional output voltage, demonstrating essential measurement techniques for current-sensing applications, photodiode interfacing, and analog signal processing. A regulated power supply ensures stable operation, while protective elements safeguard the apparatus from overvoltage, overcurrent, and incorrect connections, making it suitable for repeated use in educational and research laboratories. Accessible test points allow observation of input and output signals using oscilloscopes, multimeters, or data acquisition systems, enabling detailed analysis of conversion accuracy, linearity, and circuit performance. By varying input signals and component values, learners can explore the effect on output current or voltage, gaining practical insights into operational amplifier behavior, linearity, gain control, and precision signal conversion. The apparatus is constructed with high-quality components and a robust frame to ensure durability, stability, and long-term usability in classrooms, technical institutes, and laboratories. Glass Agencies maintains strict quality control to ensure reliable, accurate, and safe operation. The Operational Amplifier as V-I & I-V Converter provides a comprehensive, interactive platform for understanding analog signal conversion, operational amplifier applications, and precision measurement techniques. It serves as an essential tool for electronics education, experimental learning, and research, offering students and researchers practical experience in V-I and I-V conversion, sensor interfacing, and applied analog electronics, making it a valuable addition to modern electronics laboratories, training programs, and technical institutes.
