The instrumentation amplifier also has some useful features like low offset voltage, high CMRR (Common mode rejection ratio), high input resistance, high gain etc. Understanding the Instrumentation Amplifier Circuit. Also, keep in mind that an amplifier's noise may not be constant over frequency, especially at a low frequency where 1/f noise can become the dominant noise source. In Medical instrumentation, Navigation, Radar instrumentation e.t.c 3. In this article, we will see the different antilog amplifier circuits, its working and antilog amplifier applications. 2. An Instrumentation amplifier is a kind of differential amplifier with additional input buffer stages. The applications of Instrumentation Amplifier are: 1. A instrumentation amplifier is a special purpose linear amplifier used to amplify low level signals. MCQs in Summing Amplifier Circuits; MCQs in Current Boosters; MCQs in Voltage Controlled Current Sources ; MCQs in Automatic Gain Control; MCQs in Single Supply Operation; Start Practice Exam Test Questions. In this post, we will discuss its configuration, operation working, and some other related parameters. The gain can be varied from 1 to 1,000 by an external resistor whose value may vary from 100 to 10 k, , determine: (a) the voltage gain, (b) the output voltage. The circuit configuration of this module is shown in the below figure. (1) shows that. VI Conclusion. Required fields are marked *, You may use these HTML tags and attributes:
, Instrumentation Amplifiers Circuit and Example, One of the most useful and versatile op amp circuits for precision measurement and process control is the, (IA), so-called because of its widespread use in measurement systems. The main features of this amplifier is its large value impedance, large common-mode rejection less output offset, and less value impedance at the output. Loads cells for measuring pressure are often used with instrumentation amplifiers because load cells are typically floating- meaning they have no direct connection to ground. Contents show. Figure 1. Instrumentation amplifiers are used where great accuracy and stability of the circuit both short and long-term are required.
