POWER SUPPLIES
The evaluation board requires that an external power supply—
either a bench top supply or a wall wart (dc plug) supply—be
applied to J4 or J5 (see Table 3 for more information). Linear
regulators generate the required power supply levels from the
applied VIN rail. The regulators used are the 5 V ADP1720 (U7)
and the 2.5 V ADP1720 (U4), which supply 5 V and 2.5 V,
respectively, to AVDD1/AVDD2 of the ADC. The 3.3 V
ADP1720 (U10) delivers 3.3 V to the IOVDD pin of the
AD7176-2.
When a split power supply is used, the AVSS voltage must be
applied from an external source via Connector J9. AVDD1/
AVDD2 and IOVDD can also be provided via Connector J9.
However, the 7 V to 9 V supply is still required because the
on-board reference (ADR445) is supplied from this power supply.
Each supply is decoupled at the point where it enters the board
and again at the point where it connects to each device (see
the schematics shown in Figure 25 to Figure 28 to identify
decoupling points).
primary signals: CS, SCLK, DIN, and DOUT/RDY (all are
inputs, except for DOUT/RDY, which is an output.)
If you wish to operate the EVAL-AD7176-2SDZ in standalone
mode, the AD7176-2 serial interface lines can be disconnected
from the 120-pin header by removing the 0 Ω links, R9 through
R13. The test points can then be used to fly-wire the signals to
an alternative digital capture setup.
ANALOG INPUTS
The EVAL-AD7176-2SDZ primary analog inputs can be applied
in two ways:
•
•
Using J8, the green screw in terminal connector on the
right hand side of the board.
Using the A0 to A4 SMB/SMA footprints on the evaluation
board.
SERIAL INTERFACE
The AIN0 to AIN3 analog inputs are routed via the AD8656
buffers to the associated input pins on the AD7176-2, and the
AIN4 analog input is connected to Connector J8 if LK5 to LK9
are removed, disabling the on-board noise test. The buffers are
configured for a gain of 2.
The AD7176-2 evaluation board connects via the SPI to the
Blackfin® ADSP-BF527 on the EVAL-SDP-CB1Z. There are four

REFERENCE OPTIONS
The EVAL-AD7176-2SDZ includes an external 5 V reference (the
ADR445) and an internal 2.5 V reference. The default operation
on the AD7176-2 is to use the internal 2.5 V reference.
The reference used for a conversion is selected by choosing the
reference in the SETUPCONx registers associated with Setup 1,
Setup 2, Setup 3, and Setup 4.
Switch between using the internal reference and external reference
by accessing the AD7176-2 register map via the evaluation software. Figure 3 shows how to select the reference source for
Setup 1, Setup 2, Setup 3, and Setup 4. Figure 4 shows the
ADCMODE register setting that enables the internal reference.
USING THE ON-BOARD AMPLIFIERS
The AD7176-2 evaluation board contains three front-end configurations. The AD8656 is provided for buffering the analog inputs
of the AD7176-2. By default, it is configured for a gain of 2, and
the front-end is selected on the evaluation board. The ADA4940-1
amplifier provides a single-ended to differential driver, whereas
the AD8475 is configured to operate as an attenuating single-ended
to differential driver. Figure 5 shows the location of the R and C
components on the AD7176-2 evaluation board. Figure 6 and
Figure 7 highlight the R and C components that are populated
on the board for each amplifier, and Table 5 to Table 7 list the
component values.

Noise Test—Quick Start Demonstration
To perform a noise test using the AD7176-2 evaluation board,
LK5 to LK9 should be inserted so that the analog inputs are
connected together. The internal reference should be enabled
and made available at the REFOUT pin. The internal reference
biases the analog inputs to an appropriate voltage.
Click ADC Setup to open the AD7176-2 Register Interface
window. The AD7176-2 should be configured as follows:
a. In the ADCMODE register, the internal reference is enabled and outputs a buffered 2.5 V to
the REFOUT pin.
b. In the CHMAP1 register, AIN2 is connected to the
positive input, AIN3 is connected to the negative
input of the ADC for this channel, and Setup 1 is
selected. Therefore, the AIN2 to AIN3 conversion is
mapped using the Setup 1 configuration.
c. Setup 1 is configured with the following register settings:
i. In the SETUPCON1 register, the external reference
is selected as the reference source for the ADC
conversion.
2.
3.
4.
11035-018

ii. In the FILTCON1 register, the output data rate is
set to 1 kHz, and the fast settling filter (Sinc5 +
Sinc1) is enabled.
iii. In the OFFSET1 register, the default offset
register value is selected.
iv. In the GAIN1 register, the factory trimmed gain
error value is selected.
Figure 21 shows the contents of this window and the state
of the AD7176-2 registers. Click OK to return to the main
window. Figure 22 shows an example of the main window
after running a noise test.
