Instrumentation Amplifiers

Instrumentation amplifiers (in-amps) are precision gain blocks that have a differential input and an output that may be differential, or single-ended with respect to a reference terminal. These devices amplify the difference between two input signal voltages while rejecting any signals that are common to both inputs. The in-amps are widely used in many industrial, measurement, data acquisition, and medical applications where dc precision and gain accuracy must be maintained within a noisy environment, and where large common-mode signals (usually at the ac power line frequency) are present. Analog Devices offers a complete line of precision, low-noise, low-power in-amps with excellent CMRR (common mode rejection ratio) for every application and market.

A Programmable Gain Instrumentation Amplifier (PGiA) is a special form of in-amp that has fixed gain levels. The appropriate gain level is selected by digital means, either by dedicated program pins, or by software interfaces (SPI or I2C). The PGiAs are perfect for those applications where gain accuracy must be maximized, or where a single PGiA can take the place of several in-amps of different gain settings.
