Electronic circuit for an electrochemical sensor and method for functional analysis of the electrochemical sensor

摘要

The invention relates to an electronic circuit (1) for an electrochemical sensor, comprising: a first circuit point (2) which is suitable for being connected to a first electrode (3) of the electrochemical sensor (17), - a second circuit point ( 4), which is suitable for being connected to a second electrode (5) of the electrochemical sensor (17), - at least one first analog-digital converter (7) with a first analog input (8) and with a first digital output ( 9), the first analog input (8) being connected to the first node (2), and the first digital output (9) being suitable for outputting a first digital signal (DS1). The electronic circuit (1) also has a digital-to-analog converter (10) with an analog output (11), the analog output (11) being connected to the second circuit point (4) and being suitable for transmitting an analog signal (AS ) output.
