The Wheatstone Click Board™ utilizes a Wheatstone Bridge circuit onboard, in order to precisely measure the resistance of an external element. Besides the Wheatstone Bridge circuit, this Click Board™ also utilizes MAX4208 – an ultra-low offset/drift, precision instrumentation amplifier, from Maxim Integrated.
Having features such as Spread-Spectrum, Auto-Zero, Low Offset Voltage Drift and more makes the mentioned IC ideal for accurate detection of very small voltage changes and conversion into a digital form. Having these features in mind, the Wheatstone Click Board™ is ideal for using in various applications which may include sensor readings and precise resistance measurements.
