Instrumentation amplifiers - the next level of precision signal conditioning

Integrated resistor networks maximize accuracy and space efficiency

Our portfolio of instrumentation amplifiers offers a wide range of options to help ensure optimized performance for a variety of applications. With cutting-edge process and thin-film technology, these products achieve very high levels of direct-current (DC) precision such as offset voltage, gain error, drift and common-mode rejection. Innovative designs enable our instrumentation amplifiers to reach unprecedented levels of speed, noise, and power while state-of-the-art packaging push the boundaries on size with 3x3-mm QFN options for maximum space savings.
