EVALUATION BOARD HARDWARE DEVICE DESCRIPTION This user guide describes the evaluation board for the AD7091R analog-to-digital converter.

The AD7091R is a 12-bit, ultralow power, successive approxima-tion ADC. The AD7091R operates from a single 2.7 V to 5.25 V power supply and is capable of achieving a throughput rate of 1 MSPS. The AD7091R also features an on-chip conversion clock, an accurate reference, and a high speed serial interface.

The conversion process and data acquisition are controlled using a CONVST signal and an internal oscillator. The AD7091R has a serial interface allowing data to be read after the conver-sion, while achieving 1 MSPS throughput rate. The AD7091R uses advanced design and process techniques to achieve ultralow power dissipation at high throughput rates. An on-chip, accurate 2.5 V reference is available.

Complete specifications for the AD7091R are provided in the AD7091R data sheet, available from Analog Devices, which should be consulted in conjunction with this user guide when using the evaluation board.

Full details on the EVAL-SDP-CB1Z are available at http://www.analog.com/EVAL-SDP-CB1Z.

HARDWARE LINK OPTIONS The functions of the link options are described in Table 2. The default setup is configured to operate the board with the mains power supply adapter and to interface to the EVAL-SDP-CB1Z board.

POWER SUPPLIES Care should be taken before applying power and signals to the evaluation board to ensure that all link positions are set according to the required operating mode. See Table 2 for the complete list of link options.

This evaluation board is supplied with a wall-mountable switching power supply that provides a 9 V dc output. Connect the supply to a 100 V to 240 V ac wall outlet at 50 Hz to 60 Hz.

The output from the supply is provided through a 2.0 mm inner diameter jack that connects to the evaluation board at J1. The 9 V supply is connected to the on-board 5 V linear regulator that supplies the correct bias to each of the various sections on the board and the EVAL-SDP-CB1Z board.

When using this evaluation board with the EVAL-SDP-CB1Z board, it is necessary to power the board through the J1 connector.

If the evaluation board is used without the 9 V adapter, an external power supply in the range of 2.7 V to 5.25 V must be connected to the VDD input to supply the AD7091R VDD pin. In addition, an external supply in the range of 1.65 V to 5.25 V must be connected to the VDRIVE input to supply the AD7091R VDRIVE pin.

Each supply is decoupled on this board using 10 µF tantalum and 100 nF multilayer ceramic capacitors.

There are two main ground planes, AGND and DGND. These are connected at one location close to the AD7091R.

Caution

When the EVAL-AD7091RSDZ evaluation board is connected to the EVAL-SDP-CB1Z, care must be taken to ensure that, if an external voltage is supplied to the VDRIVE input connector, J3, the voltage does not exceed 3.3 V. Otherwise, permanent damage may occur to the EVAL-SDP-CB1Z board.

EVAL-AD7091RSDZ BASIC HARDWARE SETUP The EVAL-AD7091RSDZ board connects to the EVAL-SDP-CB1Z system demonstration platform board. The EVAL-SDP-CB1Z board is the controller board, which is the communication link between the PC and the main evaluation board. Figure 2 shows a photograph of the connections between the EVAL-AD7091RSDZ daughter board and the EVAL-SDP-CB1Z board.

The analog input range to the AD7091R is 0 V to VREF and should not be exceeded. When using the on-chip reference, VREF is 2.5 V. An input signal in the range of 2.5 V p-p should be connected to the EVAL-AD7091RSDZ board via VIN or VINB.

A bipolar input signal should be connected to VINB, the J6 connector. This signal is biased to 1.25 V via the bias up circuitry on the EVAL-AD7091RSDZ. The signal source should be a low impedance source. An on-board unity gain amplifier buffers the signal to the AD7091R. This is the default configura-tion on the EVAL-AD7091RSDZ.

A unipolar input signal should be connected to VIN, the J5 connector. An on-board unity gain amplifier buffers the signal to the AD7091R.

Before connecting power, connect the EVAL-AD7091RSDZ board to Connector A on the EVAL-SDP-CB1Z board. A nylon screw/nut set is included in the EVAL-AD7091RSDZ kit and can

be used to ensure that the EVAL-AD7091RSDZ and EVAL-SDP-CB1Z boards are connected firmly together.

Ensure that the link options are in the default positions as outlined in Table 2.

After the EVAL-AD7091RSDZ board and the EVAL-SDP-CB1Z board are connected securely, connect the power to the EVAL-AD7091RSDZ board. The EVAL-AD7091RSDZ board requires an external power supply adapter, which is included in the evaluation board kit. Connect this power supply to Connector J1 on the EVAL-AD7091RSDZ board. For further details on the required power supply connections and options, see the Power Supplies section.

Before connecting the EVAL-SDP-CB1Z board to your PC, ensure that the EVAL-AD7091RSDZ software has been installed from the enclosed CD. The full software installation procedure is detailed in the Evaluation Board Software section.

Finally, connect the EVAL-SDP-CB1Z board to the PC via the USB cable enclosed in the EVAL-SDP-CB1Z kit. If using a Windows XP platform, you may need to search for the EVAL-SDP-CB1Z drivers. Choose to automatically search for the drivers for the EVAL-SDP-CB1Z board if prompted by the operating system.

Figure 17. FFT Capture Tab

AC TESTING—FFT CAPTURE Figure 17 shows the FFT capture tab. This tests the traditional ac characteristics of the converter and displays a fast Fourier transform (FFT) of the results. As in the histogram test, raw data is captured and passed to the PC where the FFT is performed, displaying SNR, SINAD, THD, and SFDR. To perform an ac test, apply a sinusoidal signal to the evaluation board at the SMB input, J5 or J6. Low distortion, better than 115 dB, is required to allow true evaluation of the part. One possibility is to filter the input signal from the ac source. There is no sug-gested band-pass filter but consideration should be taken in the

choice. Furthermore, if using a low frequency band-pass filter when the full-scale input range is more than a few volts peak to peak, it is recommended to use the on-board amplifiers to amplify the signal, thus preventing the filter from distorting the input signal.

Figure 17 displays the results of the captured data.

• Section 1 shows the input signal information. • Section 2 displays the fundamental frequency and

amplitude in addition to the 2nd to 5th harmonics. • Section 3 displays the performance data: SNR, dynamic

range, THD, SINAD, and noise performance.
