Digital programmable instrumentation amplifier
(КПІ ім. Ігоря Сікорського, 2021) Burkovskiy, Y.; Zinkovskiy, U.
The subject matter of study in the article is schematic solutions of instrumentation amplifiers with a programmable gain for applied solutions. The goal is the creation of the circuitry that implements a programmable instrumentation amplifier that combines the advantages of already-known solutions with the possibility of setting the necessary gain through a digital I2C / SPI interface. The following results are obtained: during the work, a new circuitry solution is proposed for the small-sized programmable instrumentation amplifier based on the differential amplifier with a fixed gain and programmable digital potentiometer. The analysis of the proposed implementation of programmable instrumentation amplifier allows us to conclude that the advantages of the proposed solution include small sizes of the developed circuitry, the ability to flexibly con-figure elements of the construction, the maximum possible range of gain, the ability to automatically calibrate the gain setup error and relative simplicity of implementation.
