Product Summary
The INA146UA/2K5 is a precision difference amplifier that can be used to accurately attenuate high differential voltages and reject high common-mode voltages for compatibility with common signal processing voltage levels. High-voltage capability also affords inherent input protection. The input common-mode range extends beyond both supply rails, making the INA146UA/2K5 well-suited for both single and dual supply applications. The applications of the INA146UA/2K5 include current shunt measurements, sensor amplifier, synchronous demodulator, current and differential line receiver, voltage-controlled current source, battery powered systems and low cost automotive instrumentation.
