QADC64E Legacy Mode Operation
In addition to internal junction leakage, external leakage (e.g., if external clamping diodes are used) and
charge sharing effects with internal capacitors also contribute to the total leakage current.
illustrates the effect of different levels of total leakage on accuracy for different values of source
impedance. The error is listed in terms of 10-bit counts.

Positive or negative stress refers to conditions which exceed nominally defined operating limits. Examples
include applying a voltage exceeding the normal limit on an input (for example, voltages outside of the
suggested supply/reference ranges) or causing currents into or out of the signal which exceed normal
limits. QADC64E specific considerations are voltages greater than V
an analog input which cause excessive currents into or out of the input. Refer to
Characteristics,” to for more information on exact magnitudes.
Either stress condition can potentially disrupt conversion results on neighboring inputs. Parasitic devices,
associated with CMOS processes, can cause an immediate disruptive influence on neighboring signals.
Common examples of parasitic devices are diodes to substrate and bipolar devices with the base terminal
tied to substrate (V
cause errors on the selected channel by developing a voltage drop across the selected channel’s
impedances.
