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 V

IN

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).

SERIAL INTERFACE

The AD7176-2 evaluation board connects via the SPI to the

Blackfin® ADSP-BF527 on the EVAL-SDP-CB1Z . There are four

EVAL-AD7176-2SDZ User Guide 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.

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 EVAL-AD7176-2SDZ software is set up to analyze dc inputs to the ADC.

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 soft-

ware. 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.

SOFTWARE OPERATION

Overview of the Main Window

The main window of the software (see Figure 20) contains the

significant control buttons and analysis indicators of the

AD7176-2 software.

ADC Setup Button

Clicking ADC Setup, located near the top left of the main

window (see Figure 20), opens the AD7176-2 Register Interface

window.

Start Sampling Button

Clicking Start Sampling, located near the top right hand corner

of the main window (see Figure 20), starts ADC sampling; results

are reported in the graphs of the DATA and ANALYSIS sections of the main window.

Data Graph

The graph in the upper half, or DATA section, of the main window, shows each successive sample of the ADC output (input referred).

EVAL-AD7176-2SDZ User Guide

The indicators beside this graph show the latest data value, the channel being converted, and the flag for the error diagnostics of the AD7176-2 . Navigation tools are provided to allow you to

control the cursor, zooming, and panning (see Figure 20).

Analysis Graph

The graph in the bottom half, or ANALYSIS section, of the main window, shows the histogram analysis; to the right of the graph, the respective noise analysis on the indicator is shown.

Navigation tools are provided to allow you to control the cursor,

zooming, and panning (see Figure 20).

CRC Error Indicator

This LED icon illuminates when there has been a CRC error detected in the communications between the software and the

AD7176-2 . The CRC functionality on the AD7176-2 is disabled by default.

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.

1. 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 refer- ence 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.

UG-478 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.

2. 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.

3. Set the number of samples to be collected in each batch in the Samples box, which is located just to the left of Start

Sampling, near the top right hand corner of the main window.

4. Click Start Sampling to acquire samples from the ADC.

Figure 22. Example of the Main Window After Running a Noise Test

Reading Samples from the ADC

The evaluation board is set up to use the external 5 V on-board reference ( ADR445 ). To read samples from the ADC,

1. The value in the Vref box is set to 5.0000 V by default to use the external 5 V on-board reference ( ADR445 ). If a different reference is used, such as the 2.5 V internal reference, set the value in the Vref box accordingly. (The analysis results are based on the value set in this box.)

2. Select the number of samples to analyze in the Samples box. (Note that when performing a continuous capture, this number is limited to 65,536 samples.)

3. When Sampling is set to Capture, a batch of samples is read when Start Sampling is clicked, with the batch size being set by the value in the Samples box. When Sampling is set to Continuous, the software performs a continuous capture from the ADC when Start Sampling is clicked.

4. Click Stop to stop streaming data.

5. Use the navigation tools within each graph to control the

cursor, zooming, and panning (see Figure 20).

6. If desired, save the current captured data for later analysis

(see Figure 24 and the Save File section).
