As the industry's first current-sense amplifier that integrates a high-precision, low-drift shunt resistor, the Texas Instruments INA250 can provide high-precision measurements over a wide temperature range.
The INA250 integrates shunt resistors with bidirectional, zero-drift current-sense amplifiers to support low- and high-end implementations. Its accuracy and low drift reduce or may eliminate calibration work for many system designers. Compared to competing solutions, this integration also reduces system costs and board-level footprint.
By achieving high-precision measurement, lower system cost, and smaller board area, the INA250 current-sense amplifier can provide higher performance for applications such as test and measurement, communication load monitoring, and power supplies. Test and measurement designers can achieve the required level of performance and have the potential to eliminate calibration while reducing costs by up to 76%. High-performance enterprises and telecommunications equipment designers can implement distributed measurements to maximize system efficiency and enhance system management.
The INA250 evaluation module (EVM) enables designers to quickly and easily evaluate the accuracy of their equipment. In addition, INA250 TINA-TI and TINA-TI Spice models can be downloaded.
