GENERAL DESCRIPTION

The
ADuCM355
on-chip system provides the features needed
to bias and to measure a range of different electrochemical
sensors. The EVAL-ADuCM355QSPZ allows users to evaluate
the performance of the
ADuCM355
range of different electrochemical techniques, including
chronoamperometry, voltammetry, and electrochemical
impedance spectroscopy (EIS).
Complete specifications for the
ADuCM355
