Introduction to AD623

• The AD623 is an instrumentation amplifier that falls under the category of differential amplifiers that incorporate buffer amplifiers attached to their input pins, making it a suitable pick for test and measurement equipment.
• This device doesn’t require impedance matching which is a practice of making one impedance appear like another.

• Rail-to-Rail feature is used in this amplifier which allows the output voltage to reach its full potential of positive rail voltage or negative rail voltage.
• In a normal amplifier, this feature is not available as the output voltage of the amplifier is not equal to the supply voltage due to the presence of stage transistors which keep the amplifier from reaching its maximum positive or maximum negative voltage. Rail-to-Rail feature is used to overcome this problem.

• Moreover, this device comes with very high input impedance, high common-mode rejection ratio, low noise, low drift, and low offset.
• This kind of amplifier is mainly employed in the circuits where remarkable stability and accuracy is required.
• Instrumentation amplifier is a type of differential amplifiers where the internal amplifiers are arranged in a way ­– one amplifier is used to generate desired output with enough impedance and the other amplifier is used to buffer each input (+,-)
• Instrumentation amplifiers can be developed using standard individual amplifiers and precision resistors but also come in an integrated chip. This AD623 amplifier comes in an integrated chip that incorporates laser-trimmed resistors that provide a remarkable common-mode rejection ratio.
