It also operates at a very low current of nA making it suitable for battery operated applications. Instrumentation amplifier: Instrumentation amplifier is a type of differential amplifier that has buffer amplifiers connected to their input pins. This eliminates the need for impedance matching, thus making it practically suitable for measurement and test equipments. Rail to Rail Op-Amp: The output pin of a normal op-amp will not be able to provide voltage that is equal to the supply voltage.

This is because of the output stage transistors which prevent the amplifier from reaching the maximum positive voltage or minimum negative voltage. Rail to Rail Op-Amp overcomes this problem and hence the output pin can reach either positive rail voltage or negative rail voltage. The AD only requires a resistor to sets its gain value and hence can be easily set up.

A very basic commonly used circuit for AD is shown below. If a dual supply voltage is used the pin 4 will be provided with negative voltage. The non - inverting pin pin 2 and the inverting pin pin 3 is connected the signal which has to be amplified or compared base on the application of the Op-Amp.

The Reference pin pin 5 is normally grounded along with pin 4, the reference pin is used to direct the output towards a voltage when the difference voltage between the inverting and the non-inverting pin is 0V. The formulae to calculate the value of gain from R is given below. Alternatively you can also use the chart below which has the value of resistor and standard gain values listed.

The AD is an integrated, single- or dual-supply instrumentation amplifier that delivers rail-to-rail output swing using supply voltages from 3 V to 12 V. The AD offers superior user flexibility by allowing single gain set resistor programming and by conforming to the 8-lead industry standard pinout configuration. The AD has a wide input common-mode range and amplifies signals with commonmode voltages as low as mV below ground. The AD maintains superior performance with dual and single polarity power supplies.
