EVAL-CN0314-EB1Z

EVAL-CN0314-EB1Z is a CN0314 circuit evaluation board. The circuit is a configurable 4mA-to-20mA loop-powered transmitter /receiver using a micropower instrumentation amplifier. It features AD8420, an instrumentation amplifier based on an indirect current feedback architecture. Because of this architecture, the AD8420 has excellent input and output characteristics. Unlike conventional instrumentation amplifiers, AD8420 can easily amplify signals at or even slightly below ground without requiring dual supplies. The AD8420 has rail-to-rail output voltage swing that is completely independent of the input common-mode voltage. This exempts the AD8420 from the restrictions caused by interaction between the common-mode input and output voltage associated with most conventional instrumentation amplifier architectures. The flexible input and output characteristics, together with micropower consumption and wide supply range, make AD8420 ideal for flexible low power industrial applications.
