ESD PROTECTION OF DIGITAL PINS AND
RESISTOR TERMINALS
The AD5258 VDD, VLOGIC, and GND power supplies define the
boundary conditions for proper 3-terminal and digital input
operation. Supply signals present on Terminal A, Terminal B,
and Terminal W that exceed VDD or GND are clamped by the
internal forward-biased ESD protection diodes (see Figure 40).
Digital Input SCL and Digital Input SDA are clamped by ESD
protection diodes with respect to VLOGIC and GND as shown in

POWER-UP SEQUENCE
Because the ESD protection diodes limit the voltage compliance
at Terminal A, Terminal B, and Terminal W (see Figure 40), it is
important to power GND/VDD/VLOGIC before applying any volt-
age to Terminal A, Terminal B, and Terminal W; otherwise, the
diode is forward-biased such that VDD and VLOGIC are powered
unintentionally and may affect the user’s circuit. The ideal
power-up sequence is in the following order: GND, VDD,
VLOGIC, digital inputs, and then VA, VB, VW. The relative order
of powering VA, VB, VW and the digital inputs is not important
as long as they are powered after GND, VDD, and VLOGIC.
LAYOUT AND POWER SUPPLY BYPASSING
It is good practice to employ compact, minimum lead length
layout design. The leads to the inputs should be as direct as
possible with minimum conductor length. Ground paths
should have low resistance and low inductance.
Similarly, it is also good practice to bypass the power supplies
with quality capacitors for optimum stability. Supply leads to
the device should be bypassed with disc or chip ceramic capaci-
tors of 0.01 F to 0.1 F. In addition, low ESR 1 F to 10 F
tantalum or electrolytic capacitors should be applied at the
supplies to minimize any transient disturbance and low fre-
quency ripple (see Figure 42). As well, the digital ground
should be joined remotely to the analog ground at one point
to minimize the ground bounce.

MULTIPLE DEVICES ON ONE BUS
The AD5258 has two configurable address pins, AD0 and AD1.
The state of these two pins is registered upon power-up and
decoded into a corresponding I2C-compatible 7-bit address (see
Table 5). This allows up to four devices on the bus to be written
to or read from independently.
