AD602AR-REEL Linear Application Field and Working Principle

The AD602AR-REEL is a high-performance, low-cost instrumentation amplifier and buffer amplifier. It is a precision, low-power operational amplifier that benefits from the combination of low offset voltage, low input bias current, and low drift. The AD602AR-REEL’s linearly adjustable gain makes it ideal for applications that require high linearity, such as data acquisition systems, automatic test equipment, and precision instrumentation, and is ideal for use in audio applications that require wide dynamic range.

The AD602AR-REEL’s high gain accuracy, low-cost, and wide applicable range make it an excellent choice for those applications that require a reliable, low-cost solution. It also has good output voltage noise performance and is suitable for applications where higher dynamic range or precision audio/signal processing is required.

BLOCK DIAGRAM

The AD602AR-REEL is a two-stage instrumentation amplifier and buffer amplifier which consists of two signal conditioning stages and a precision output buffer amplifier. The first stage amplifies the signal accurately enough to minimize the effects of any noise picked up by the signal.

The second stage is an operational amplifier that provides the coefficient OVF required to correctly set the gain of the amplifier. This is done by connecting a resistor between the output of the first stage and the second stage. The output of the second stage is then connected to the output buffer amplifier. The supplied voltage gain can then be adjusted with the coefficient OVF resistor.

WORKING PRINCIPLE

The AD602AR-REEL operates as an instrumentation amplifier and buffer amplifier, has a wide operating range, and can achieve a wide range of gains. The two isolated inputs allow for differential voltage sampling. The non-inverting input of the instrumentation amplifier is connected to the input voltage, and the inverting input is connected to a gain control resistor.

The input signals are then amplified by the instrumentation amplifier by the gain set by the gain control resistor. The output voltage is then connected to an output buffer amplifier which provides the desired output voltage. The output buffer amplifier can be used as a differencing amplifier to improve the accuracy of the instrumentation amplifier.

The AD602AR-REEL can be used to amplify virtually any type of signal, including signals with high bandwidth, low frequencies, and low noise. The gain is adjustable and can be set by adjusting the resistor connected to the inverting input of the instrumentation amplifier.
