AD526

GROUNDING AND BYPASSING

Utilizing the force and sense outputs of the AD526, as shown in

Figure 38, avoids signal drops along etch runs to low impedance

loads.

Proper signal and grounding techniques must be applied in

board layout so that specified performance levels of precision

data acquisition components, such as the AD526, are not

degraded.

Table II. Logic Table for Figure 38

V_OUT/V_IN

As is shown in Figure 37, logic and signal grounds should be

separate. By connecting the signal source ground locally to the

AD526 analog ground Pins 5 and 6, gain accuracy of the

AD526 is maintained. This ground connection should not be

corrupted by currents associated with other elements within the

system.
