SDA 9254-2
Application Circuit
For best performance and operation within the specified AC parameter limits it is mandatory to use
separate decoupling capacitors for V_SS1/V_DD1 and V_SS2/V_DD2 with V_SS1 shorted to V_SS2 and V_DD1
shorted to V_DD2 on the board as shown in figure below.
Decoupling capacitors C₁ and C₂ of low inductance multilayer type (at least 0.1 µF) should be used.
To avoid malfunction or even permanent damage of the device it is strongly recommended not to
use any other supply configuration.
