ADIS16136
APPLICATIONS INFORMATION
POWER SUPPLY CONSIDERATIONS
The ADIS16136 includes 12 µF of capacitance across the VDD
and GND pins. This capacitance presents low input impedance
for power supplies that have fast rise times. The internal power
regulator waits for a valid input supply voltage, and then goes
through a start-up process that draws an elevated current
(~400 mA) for approximately 1.5 ms. This transient current
occurs approximately 125 ms after VDD reaches a valid level.
This regulation circuit also provides a constant power load,
which results in a load that has a negative dynamic resistance.
Figure 21 provides a graphical relationship between the supply
current and voltage for systems that need to account for this
type of load when designing supply feedback loops.

PROTOTYPE INTERFACE BOARD
The ADIS16136/PCBZ includes one ADIS16136AMLZ, one
interface PCB, and four M2 × 18 machine screws. The interface
PCB provides larger connectors than the ADIS16136AMLZ for
simpler prototyping, four tapped M2 holes for attachment of the
ADIS16136AMLZ, and four holes (machine screw size M2.5 or
No. 4) for mounting the ADIS16136AMLZ to a solid structure.
J1 and J2 are dual row, 2 mm (pitch) connectors that work with
a number of ribbon cable systems, including 3M Part Number
152212-0100-GB (ribbon crimp connector) and 3M Part Number
3625/12 (ribbon cable).
Data Sheet
Figure 22 provides the top level view of the interface board.
Install the ADIS16136AMLZ onto this board using the silk
pattern as an orientation guide. Figure 23 provides the pin
assignments for J1 and J2. The pin descriptions match those
listed in Table 5. The ADIS16136 does not require external
capacitors for normal operation; therefore, the interface printed
circuit board (PCB) does not use the C1 and C2 pads.
