Instrumentation Amplifiers, Analog Devices
The Instrumentation Amplifier ICs amplify the difference between two input signal voltages, while rejecting any signals that are common to both inputs. The DC precision and gain accuracy is maintained within a noisy environment, and also where large common-mode signals (AC power line frequency) are present.
A range of Instrumentation Amplifiers from Analog Devices. This range of products also includes numerous evaluation and development boards.
