Precision Difference Amps Handle High Voltages

Designed for low-cost applications in industrial process control, test and measurement, medical diagnostic instrumentation, telecomm, data acquisition, and signal transmission systems, the INA145 and INA146 programmable-gain precision difference amplifiers allow the user freedom to set gain without adding an additional amp. This proves especially beneficial in portable and multi-channel systems where bulky discrete circuits can be replace with one surface-mount package. In addition, the chips offer faster design time, reduced board space, simplified assembly, and improved reliability. For high-voltage requirements, the INA146 is capable of handling up to ±100V differential and common-mode inputs. The input common-mode range extends beyond both supply rails, making the devices suited for both single and dual supply applications. The devices come in a SO-8 SMT package.
