A typical circuit connection for six-channel analog in and eight-channel analog out is shown in Figure 56.
C1 through C6 are 1-F ceramic capacitors dependent on power-supply quality. C7 and C8 are 10-F electrolytic capacitors dependent on
power-supply quality. C9 and C10 are 10-F electrolytic capacitors. C11 and C12 are 10-F electrolytic capacitors. R1 through R12 are 22- to
100-
resistors.
Figure 56. Example Board Layout
Termination for mode control: any one of the circuits shown in Figure 57 must be applied according to the
necessary mode/configuration. Resistor value must be 220 k
, ±5% tolerant. The PowerPAD must be tied to the
ground plane with enough electrical and thermal conductivity; see the example board layout in Figure 56.
