DAC5674 EVM Operational Procedure
The DAC5674 EVM can be set up in a variety of configurations to
accommodate a specific mode of operation. Before starting evaluation, the
user should decide on the configuration and make the appropriate
connections or changes. The demonstration board comes with the following
factory-set configuration:
-
Differential clock mode using transformer T2 and a clock input at J4
-
Transformer coupled output using transformer T1
-
The converter is set to operate with internal reference. Jumper W2 is
installed between pins 1 and 2.
-
Full-scale output current set to 20 mA through R
BIAS
resistor R1
-
The DAC5674 output is enabled (sleep mode disabled). Jumper W3 is
installed between pins 1 and 2.
-
Reset operation controlled through S1. Jumper W5 is installed between
pins 2 and 3.
-
Internal PLL is disabled. Jumper W4 is installed between pins 1 and 2.
