counter electrode is configured as a transimpedance
amplifier to measure the current. Figure 25 shows a three
electrode potentiostat application that is driven at all the
electrodes and measured at the working electrode. With
this application, the DAC connected to the working elec-

trode sets the bias voltage relative to the reference elec-
trode and also measures the current that the sensor pro-
duces. The DAC connected to the reference and counter
electrodes takes advantage of the force/sense outputs to
