A | Page 5 of 26 UG-1435 EVAL-AD4112SDZ User Guide SERIAL INTERFACE ANALOG INPUTS The EVAL-AD4112SDZ board connects via the serial peripheral interface (SPI) to the Blackfin(R) ADSP-BF527 on the SDP-B board. There are four primary signals, three inputs (CS, SCLK, and DIN) and one output from the ADC (DOUT/RDY). There are two types of analog inputs: voltage and current. The EVAL-AD4112SDZ evaluation board connects to the EVAL-ADuCM3029EZ-KIT the same way. Connecting the evaluation board to the EVAL-ADuCM3029EZ-KIT allows the user to develop their own C code rather than using the provided evaluation software. To operate the EVAL-AD4112SDZ in standalone mode, disconnect any board connected to J8 and use J10 to access all SPI signals and set the input/output voltage levels. POWER SUPPLIES By default, the board is powered from the SDP-B connector. The board can be also powered from the J6 and J7 connectors by setting LK3 to Position A or from Pin +5V on Connector J10 (see Table 2). The ADuM5411 isoPower(R) digital isolator is used to isolate power and data lines up to 2.5 kV rms. Eight voltage inputs are available on J1 and J2. Four current inputs are available on J3. If a different common voltage must be set for single-ended measurement, remove LK2 and connect the desired voltage to V_COM on J1. REFERENCE OPTIONS The EVAL-AD4112SDZ includes an external 2.5 V reference, the ADR4525ARZ. By default, LK1 is inserted, connecting the external reference to REF+ of the AD4112. Remove LK1 if using a different single-ended external reference. In the evaluation software, click the blue pop-up button associated with Setup 0 to Setup 7 to select the reference used for conversions by the AD4112. The pop-up button is located below the external reference controls in the block diagram (Label 9 in Figure 16). Table 2.

Configuration Tab in Advanced Mode SOFTWARE OPERATION Overview of the Main Window After selecting AD4112 Evaluation Board, the main window of the evaluation software displays, as shown in Figure 16. This tab shows the control buttons and analysis indicators of the AD411X Eval+ software. The main window of the AD411X Eval+ software in Quickstart mode contains five tabs: Configuration, Voltage Waveform, Current Waveform, Noise Table, and Histogram. In advanced mode, two additional tabs are available: Ch Waveform and Registers. CONFIGURATION TAB The Configuration tab shows a block diagram of the AD4112. This tab allows the user to select inputs, set up the ADC, reset the ADC, view errors present, and configure the device for different demonstration modes. Figure 16 shows the Configuration tab in detail, and the following sections discuss the different elements on the Configuration tab of the software window. Inputs (Quickstart Mode Only) The AD4112 has eight voltage inputs, which can be configured as single-ended or fully differential pairs, and four current inputs (Label 1 in Figure 16). provides more realistic values for P - P Resolution and RMS Resolution shown in the Noise Analysis area (Label 22 in Figure 18). Output Data Rate (ODR)/Measurement Time The ODR can be set for all inputs in the Configuration tab (Label 2 in Figure 16). Set the ODR by entering a value in hertz into the ODR(Hz) box or a measurement time in milliseconds into the Time(ms) box. If an ODR is entered, the software calculates the measurement time. If a time is entered, the software calculates the fastest ODR that can achieve the required measurement time. The device only supports a certain number of ODRs. Therefore, the software rounds up to the closest available value. ODR values depend on if a single or multiple channels are enabled. The fastest ODRs are available if only one channel is enabled. The values shown are valid for the sinc5 + sinc1 filter, which is enabled by default. If the sinc3 filter is enabled instead, refer to the AD4112 data sheet for the corresponding values. The value in the Time(ms) box represents time taken for one sample for one enabled channel. The value in the Total Time box represents the total time to take one sample for all enabled Inputs. The voltage range can also be set per input to 10 V, 5 V, 0 V to 10 V, or 0 V to 5 V. Changing the appropriate voltage range Rev. A | Page 10 of 26 EVAL-AD4112SDZ User Guide UG-1435 Demo Modes External Parameters The AD411X Eval+ software contains a number of demonstration modes in the Demo Modes area (Label 3 in Figure 16). These demonstration modes configure the AD4112 for each of the input types (represented by the All Single-Ended, All Differential, and All Current buttons). There are three external parameters that are set by the EVALAD4112SDZ board but must be entered into the software: the external reference (Label 8 in Figure 16), AVDD (Label 9 in Figure 16), and AVSS (Label 10 in Figure 16). The external reference on the EVAL-AD4112SDZ board is set to 2.5 V by using an ADR4525. If bypassing the ADR4525 on board, change the external reference voltage value in the software to ensure correct calculation of results in the Waveform and Histogram tabs.

Voltage Waveform Tab WAVEFORM TABS Sample The AD411X Eval+ software has three different waveform tabs: Voltage Waveform, Current Waveform, and Ch Waveform (in advanced mode only). The waveform tabs graph the conversions gathered and processes the data, calculating the peak-to-peak noise, rms noise, and resolution (see Figure 18). The Voltage Waveform tab graphs the data at the voltage input. The Current Waveform tab graphs the data at the current inputs, which are displayed in amps. The Ch Waveform tab displays both voltage and current inputs as voltages. Click Sample (Label 17 in Figure 18) to start gathering ADC results. Results appear in the waveform graph. Waveform Graph and Controls Display Units and Axis Controls The data waveform graph (Label 13 in Figure 18) shows each successive sample of the ADC output. Zoom in on the data in the graph using the control buttons (Label 14 in Figure 18). Change the scales on the graph by typing values into the x-axis and y-axis. Click the Units box in the Graph Configuration area (Label 19 in Figure 18) to select whether the data graph displays in units of voltage in amps or codes. This control is independent for each graph. The Y-scale and X-scale boxes can be set to autoscale or fixed scaling. When Autoscale is selected, the axis automatically adjusts to show the entire range of the ADC results after each batch of samples. When Fixed is selected, the axis range can be set by the user. These ranges do not automatically adjust after each batch of samples. Samples The Samples box (Label 15 in Figure 18) and Sampling Mode (Label 16 in Figure 18) set the number of samples gathered per batch. If Sampling Mode is set to Single Capture, the ADC returns the number of samples specified in the Samples box. If Sampling Mode is set to Continuous, the ADC continuously returns samples until stopped by the user. Samples specifies the amount of samples to be shown on the data graph. Samples is unrelated to the ADC mode. Plot Selection The plot selection control area (Label 18 in Figure 18) allows the user to select which inputs display on the data waveform and shows the name of the input. These controls only affect the waveform graphs and have no effect on the channel settings in the ADC register map. Rev.
