SERIAL INTERFACE

The EVAL-AD7172-4SDZ connects via the serial peripheral
interface (SPI) to the Blackfin®
CB1Z. There are four input signals: CS , SCLK, DIN, and SYNC ,
and one output signal from the ADC, DOUT/ RDY (see Figure 1).
To operate the EVAL-AD7172-4SDZ
disconnect the evaluation board from the
controller board. Use the test points labeled on the
AD7172-4SDZ to connect the signals to an alternative digital
capture setup or the Pmod-compatible header (A7).

POWER SUPPLIES

Power the EVAL-AD7172-4SDZ
connected to J5, or from an external bench top supply applied
to J3 or J9. Linear LDO regulators generate the required
voltages from the applied input voltage (V
or J5. Use J9 to bypass the on-board regulators. An
regulator generates the 5 V (single-supply) and 2.5 V (split
supply) supplies for the AVDD1 and AVDD2 rails to the ADC;
a second ADP7118
ADP7104 supplies 5 V for the
board as well as 5 V for the
generate −5 V to supply the ADP7182. The
the −2.5 V supply for AVSS when operating in split supply
mode. Each supply is decoupled where it enters the board and
again at each device in accordance with the schematic (available
for download at http://www.analog.com/EVAL-AD7172-4,
including a bill of materials). Table 3 shows the various power
supply configurations available, including split supply
operation.
