EVALUATION BOARD CIRCUITRY
The EVAL-AD5676SDZ / EVAL-AD5676RSDZ evaluation
boards allow the function and performance of the AD5676 /
AD5676R to be easily tested. Each evaluation board contains two
voltage regulators that generate the analog and digital power
supplies and that also power the
SDP-B board, if it is connected.
The two regulators are powered via a 6 V supply attached to
Connector J3. Alternatively, a separate analog supply can be
attached via Connector J2, and an external V
LOGIC
supply can be
connected to Connector J1.
Control of the AD5676 / AD5676R is typically performed by the
SDP-B board, which is attached to Connector J4. The SDP-B
board allows the software provided with the kit to be used to
load register values, set the voltage of the DAC outputs, and
write to the control register of the
AD5676 / AD5676R . When
the SDP-B board is not required, the control signals can be
applied to the AD5676 / AD5676R by connecting them to the
relevant pins on Connector J5.
The DAC output voltages are available on the SMB connectors,
VOUT0 to VOUT7.
