Self-Biased Two-Electrode
Potentiostat Application
See the circuit in
Figure
10 for an illustration of how to
use the MAX5515 to bias a two-electrode potentiostat
on the input of an ADC.
Power Supply and
Bypassing Considerations
Bypass the power supply with a 0.1μF capacitor to GND.
Minimize lengths to reduce lead inductance. If noise
becomes an issue, use shielding and/or ferrite beads to
increase isolation. For the thin QFN package, connect the
exposed pad to ground.
Layout Considerations
Digital and AC transient signals coupling to GND can
create noise at the output. Use proper grounding tech-
niques, such as a multilayer board with a low-inductance
ground plane. Wire-wrapped boards and sockets are not
recommended. For optimum system performance, use
printed circuit (PC) boards. Good PC board ground lay-
out minimizes crosstalk between DAC outputs, reference
inputs, and digital inputs. Reduce crosstalk by keeping
analog lines away from digital lines.
