A n Figure 2. CS5505/6 and CS5507/8 Pin Layouts

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

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

e e switched on (closed) and then open to cause the

CONV signal to transition low to high. This

g c latches the A0 and A1 channel selection into the

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

converter will convert continuously.
