The INA145 and INA146 are ideal for monitoring voltage and current in battery and power supply equipment such as telephone line monitors, medical instrumentation and imaging, and industrial robotics and control systems. These products are unique among difference amps because they allow the user freedom to set gain without adding an additional amplifier. The INA146 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 INA145 and INA146 well suited for both single and dual supply applications.

V common-mode signals without catastrophic destruction. These chips will work continuously at these voltages. So, if you need to measure low voltages developed across shunts in high-current metering applications or measure outputs of high voltage power supplies, for example, these devices should be able to handle such tasks effectively. What's more, laser trimming ensures that any differential measurment you take will be maintained for gain and CMR accuracy over time and temperature. These ICs should find a home in test sets, test fixtures, and sensor circuits where the input common-mode voltage range needs to extend far beyond the rails.
