The 7Semi TP5551 Current to Voltage Converter Module is a precision analog signal conditioning board designed to convert low-level current signals into proportional voltage outputs for measurement, monitoring, and control applications. Built around the TP5551 zero-drift operational amplifier, this module provides exceptional accuracy, ultra-low offset voltage, and long-term stability, making it ideal for precision instrumentation, industrial sensors, process control systems, and embedded analog measurement applications. The onboard circuitry simplifies current-to-voltage conversion, allowing engineers and developers to interface current-output sensors directly with ADCs, microcontrollers, data acquisition systems, and industrial controllers.
The TP5551 utilizes advanced chopper-stabilized zero-drift amplifier technology to achieve ultra-low offset voltage and near-zero temperature drift. This enables highly accurate signal conversion even in environments where temperature variations and long-term stability are critical concerns. With rail-to-rail input and output operation, the module can maximize the usable signal range while maintaining excellent measurement accuracy. The wide operating voltage range and low-power architecture make it suitable for battery-powered devices, portable instrumentation, sensor interfaces, and precision embedded systems.
This module is ideal for 4-20mA current loop sensing, industrial transmitters, environmental monitoring systems, laboratory instrumentation, process automation, pressure sensors, current-output transducers, data loggers, energy monitoring equipment, and analog signal acquisition applications. The compact design and JST connector interface simplify system integration while providing reliable performance across a wide range of operating conditions. Designed for dependable operation in industrial and embedded environments, the board supports an operating temperature range of -40°C to +80°C.
