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

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

switched on (closed) and then open to cause the

e e CONV signal to transition low to high. This

g c latches the A0 and A1 channel selection into the

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

n n converter will convert continuously.
