The AD7175-2 has a maximum channel-to-channel scan rate of 50 kSPS (20 µs) for fully settled data The output data rates range from 5 SPS to 250 kSPS. The device includes integrated rail to rail analog input and reference input buffers, an integrated precision 2.5 V reference, and an integrated oscillator. See the AD7175-2 data sheet for complete specifications. Consult the data sheet in conjunction with this user guide when using the evaluation board. Full details for the EVAL-SDP-CB1Z are available on the Analog Devices website. HARDWARE LINK OPTIONS See Table 1 for default link options. By default, the board is configured to operate from the supplied 9 V ac-to-dc adapter connected to connector J5. The 5 V supply required for the AD7175-2 comes from the on-board low dropout regulator (LDO). The ADP7118, with a 5 V output voltage, receives its input voltage from J3 or J5 (depending on the position of LK2) and generates a 5 V output. Table 1. Default Link and Solder Link Options Link LK1 Default Option A LK2 LK5 to LK9 B Inserted SL1 A SL2 A SL3 SL4 A A SL5 B SL8 A SL9 A SL10 A SL11 A R49 to R51 Inserted Description Selects the voltage applied to the power supply sequencer circuit (U3); dependent on AVDD1. Place in Position A if using 5 V AVDD1, or Position B if using 2.5 V AVDD1. Selects the external power supply from Connector J3 (Position A), or J4 (Position B). Inserting these links sets up the on-board noise test. In this mode, all inputs short to the common voltage via SL11. Sets the voltage applied to the AVDD2 pin. Operates using the AVDD1 supply (default). Position B sets the AVDD2 voltage to 3.3 V supply from the ADP7118 (3.3 V) (U10) regulator. Selects between an external or on-board AVDD1 source. Supplies AVDD1 from the ADP7118 (5 V) (U7) (default). Selects between an external or on-board AVSS source. Supplies AVSS from the ADP7182 (-2.5 V) (U4) (default). Connects AIN4 to: A4 / J6 (Position A), REFOUT pin on the AD7175-2 (Position B) or AVSS (Position C). Positions B and C are used to simplify using a single ended input source. Selects between an external or on-board IOVDD source. Supplies IOVDD from the ADP7118 (3.3 V) (U10) (default). The evaluation board operates with a 3.3 V logic. Routes A0 to: AIN0 pin on the AD7175-2 (Position A), Buffer/Inamp U8 (Position B), Funnel Amp U9 with gain of 0.8x (Position C) or J10-1 (Position D). Routes A2 to: AIN2 pin on the AD7175-2 (Position A), Buffer U12 (Position B) or Funnel Amp U9 gain of 0.4x (Position C). Routes A3 to: AIN3 pin on the AD7175-2 (Position A), Buffer U12 (Position B) or Funnel Amp U9 gain of 0.4x (Position C). Routes A1 to: AIN1 pin on the AD7175-2 (Position A), Buffer/Inamp U8 (Position B), Funnel Amp U9 with gain of 0.8x (Position C) or J10-7 (Position D). Connects AVSS and AGND for single-supply operation. To operate in split supply mode, remove these links. Rev.

SERIAL INTERFACE POWER SUPPLIES The AD7175-2 evaluation board connects via the serial peripheral interface (SPI) to the Blackfin® ADSP-BF527 on the EVAL-SDP-CB1Z. There are four primary signals: CS, SCLK, and DIN (all inputs), and one output from the ADC, DOUT/RDY. Power the evaluation board from the ac-to-dc adapter connected to J5, or from an external bench top supply applied to J3 or J9. Linear LDOs generate the required voltages from the applied input voltage (VIN) rail when using J3 or J5. Use J9 to bypass the on-board regulators. An ADP7118 regulator is used to generate the 5 V (single supply) and 2.5 V (split supply) supplies for the AVDD1 and AVDD2 rails to the ADC; a second ADP7118 generates 3.3 V for the IOVDD rail. The ADP7104 supplies 5 V for the SDP-B controller board as well as 5 V for the ADM660 voltage converter to generate -5 V to supply the ADP7182. The ADP7182 generates 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. Table 3 shows the various power supply configurations available, including split supply operation. To operate the EVAL-AD7175-2SDZ in standalone mode, disconnect the evaluation board from the SDP-B controller board. Use the test points to connect the signals to an alternative digital capture setup or the PMOD compatible header (A7). Rev. Pr.C | Page 5 of 12 UG-AD7175-2 EVAL-AD7175-2SDZ User Guide Table 3. Power Supply Configurations 1 Configuration Single Supply (Regulated) Input Voltage Range 7 V to 9 V Single Supply (Unregulated) 7 V to 9 V, 5 V, and 3.3 V Split Supply (Regulated) 7 V to 9 V and −2.5 V Split Supply (Unregulated) 7 V to 9 V, ±2.5 V, and 3.3 V 1 Description The 7 V to 9 V input is regulated to 5 V for AVDD1/AVDD2 and 3.3 V for IOVDD. This also powers the external 5 V reference. See the Single Supply (Regulated) section in the Power Supply Configurations section. The input is unregulated and connects directly to AVDD1/AVDD2 and IOVDD from J5. The 7 V to 9 V input powers the external 5 V reference. See the Single Supply (Unregulated) section in the Power Supply Configurations section. The 7 V to 9 V input is regulated to 2.5 V for AVDD1/AVDD2 and 3.3 V for IOVDD. The 7 V to 9 V input powers the external 5 V reference, and the −2.5 V input is connected to AVSS directly (unregulated). See the Split Supply (Regulated) section in the Power Supply Configurations section. The input is unregulated and connects directly to AVDD1/AVDD2 and IOVDD from J5. The 7 V to 9 V input powers the external 5 V reference. See the Split Supply (Unregulated) section in the Power Supply Configurations section. Only one configuration can be used at a time. POWER SUPPLY CONFIGURATIONS Set all other links and solder links to the default settings as outlined in Table 1. Single Supply (Regulated) There are two available power supply options for the single supply (regulated) configuration. Split Supply (Unregulated) • 1. 2. 3. 4. 5. 6. 7. 8. • To set up the board, use the following procedure: An ac-to-dc adapter (included) connected to J5. Set LK2 to Position B. A bench top power supply connected to J3. Set LK2 to Position A and ensure that AVSS = AGND = 0 V. Set all other links and solder links to the default settings as outlined in Table 1. Single Supply (Unregulated) To set up the board, use the following procedure: 1. 2. 3. 4. 5. 6. Move SL2 and SL5 to Position A. Connect the two terminals of J9 labeled AGND and AVSS. Connect 0 V (GND) to J9 at the terminal labeled AGND. Connect 5 V to J9 at the terminal labeled AVDD. Connect 3.3 V to J9 at the terminal labeled IOVDD. Connect the 7 V to 9 V input to J5. Set all other links and solder links to the default settings as outlined in Table 1. Split Supply (Regulated) To set up the board, use the following procedure: 1. 2. 3. 4. 5. Remove R49 to R51. These links connect AVSS to AGND. Insert a zero ohm resistor for R85. Set LK1 to Position B. This sets the input to the power monitor circuitry to work with the lower AVDD1 supply of 2.5 V. Connect a bench top power supply to J5 and set LK2 to Position B. Set LK1 to Position B. This sets the input to the power monitor circuitry to work with the lower AVDD1 supply of 2.5 V. Move SL2, SL3 and SL5 to Position A. Remove R49-R51. Connect 0 V (GND) to J9 at the terminal labeled AGND. Connect 2.5 V to J9 at the terminal labeled AVDD. Connect −2.5 V to J9 at the terminal labeled AVSS. Connect 3.3 V to J9 at the terminal labeled IOVDD. Connect 7 V to 9 V to J5. Set LK1 to Position B. This sets the input to the power monitor circuitry to work with the lower AVDD1 supply of 2.5 V. Set all other links and solder links set to the default settings as outlined in Table 1. ANALOG INPUTS The EVAL-AD7175-2SDZ primary analog inputs can be applied in two separate ways. • • J6 connector on the left side of the board A0 to A4 SMB/SMA footprints on the evaluation board The analog inputs route directly to the associated analog input pins on the AD7175-2, provided that the LK5 to LK9 links (onboard noise test) are removed. The EVAL-AD7175-2SDZ software is set up to analyze dc inputs to the ADC. The AD7175-2 input buffers work for dc input signals. REFERENCE OPTIONS The EVAL-AD7175-2SDZ includes an external 5 V reference, the ADR445. The AD7175-2 includes an internal 2.5 V reference. The default operation is to use the external reference input, which is set to accept the 5 V ADR445 on the evaluation board. Rev.
