MAX19527 Evaluation Kit

12_ _ ______________________________________________________________________________________

To maintain the ADC’s current register content, place

shunts across pins 1-3 of JU11, JU12, and JU13.

Shutdown (SHDN)

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.

Connecting the DCEP to 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.

Using the DCEP with the EV Kit

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, 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.
