for A0 and A1 (see Table 1). Once A0 and A1

are selected, the CONV switch (S2-3) must be

switched on (closed) and then open to cause the

converter. With CONV high (S2-3 open) the

converter will convert continuously.

Figures 3 and 4 illustrate the evaluation board

layout while Figure 5 illustrates the component

placement (silkscreen) of the evaluation board.
