MAX19527 Evaluation Kit
To maintain the ADC’s current register content, place
shunts across pins 1-3 of JU11, JU12, and JU13.
The ADC can also be placed in a low-power shutdown
mode through jumper JU9. The SHDN pin is a toggle
switch between two power-management states, shown
in Figure 2 under the Power_ Management group box
of the software interface. When a shunt is installed on
pins 1-2 of JU9, SHDN is connected to AVDD and the
user can select the appropriate settings for inputs IN1_
Active–IN8 Active and Sleep/Nap_Mode under the label
**Use_when_SHDN_=_1_(IC_bump_B10)**. When a shunt
is installed on pins 2-3 of JU9, SHDN is connected to
GND and the user can select the appropriate settings
for inputs IN1_Active–IN8_Active and Sleep/Nap_Mode_
under the label **Use_when_SHDN_=_0_(IC_bump_B10)**.
See Table 9 for proper JU9 configuration for shutdown
control of the EV kit.

The DCEP and EV kit board can be connected using the
specified on-board connectors. H1 on the EV kit mates
with J5 on the DCEP board. Alternatively, the two boards
can be connected with coaxial ribbon cables (Samtec,
part no. HQCD-060.00-STR-TBR-1). Note that it is neces-
sary to use either the on-board connectors or cables to
obtain a reliable electrical connection between the two
boards.
Maxim’s DCEP is required for evaluation of this EV kit.
An EV kit-specific device module file is required to con-
figure the DCEP software. The most up-to-date device
module file can be downloaded from
com/evkitsoftware. When loading the DCEP device
module file, select MAX19527-EVK-xx.dsm and verify
that the device module GUI window corresponds to
Figure 5. Refer to the Opening a New Database section
in the Data Converter Evaluation Platform (DCEP) User’s
Guide for additional information.
