MAXIMIZING PERFORMANCE THROUGH PROPER
LAYOUT
To achieve the maximum performance of the extremely high
input impedance and low offset voltage of the AD823A, care
should be taken in the circuit board layout. The PCB surface
must remain clean and free of moisture to avoid leakage currents
between adjacent traces. Surface coating of the circuit board
reduces surface moisture and provides a humidity barrier, reducing
parasitic resistance on the board. The use of guard rings around the
amplifier inputs further reduces leakage currents. Figure 48 shows
how the guard rings should be configured, and Figure 49 shows
the top view of how a surface-mount layout can be arranged. The
guard ring does not need to be a specific width, but it should form
a continuous loop around both inputs. By setting the guard ring
voltage equal to the voltage at the non-inverting input, parasitic
capacitance is minimized as well. For further reduction of leakage
currents, components can be mounted to the PCB using Teflon
standoff insulators.
