Preliminary Technical Data  
device should be bypassed with disc or chip ceramic capacitors  
of 0.01 µF to 0.1 µF. Low ESR 1 µF to 10 µF tantalum or  
electrolytic capacitors should also be applied at the supplies to  
minimize any transient disturbance and low frequency ripple  
(see Figure 23). Note that the digital ground should also be  
joined remotely to the analog ground at one point to minimize  
the ground bounce.  
POWER-UP SEQUENCE  
Since the ESD protection diodes limit the voltage compliance at  
terminals A, B, and W (see Figure 22), it is important to power  
VDD/GND before applying any voltage to terminals A, B, and Wꢀ  
otherwise, the diode will be forward biased such that VDD will be  
powered unintentionally and may affect the rest of the users  
circuit. The ideal power-up sequence is in the following order:  
GND, VDD, digital inputs, and then VA/B/W. The relative order of  
powering VA, VB, VW, and the digital inputs is not important as  
long as they are powered after VDD/GND.

LAYOUT AND POWER SUPPLY BYPASSING  
GND  
It is a good practice to employ compact, minimum lead length  
layout design. The leads to the inputs should be as direct as  
possible with a minimum conductor length. Ground paths  
should have low resistance and low inductance.  
Figure 23. Power Supply Bypassing  
Similarly, it is also a good practice to bypass the power supplies  
with quality capacitors for optimum stability. Supply leads to the
