MAX1115X/MAX1116X Family Evaluation Kit Evaluates: MAX11150/MAX11152/MAX11158/ MAX11160/MAX11161/MAX11162/MAX11163/ MAX11168/MAX11169 General Description The evaluation kit (EV kit) demonstrates the MAX1115X/ MAX1116X family of 18-/16-bit SAR ADCs. The EV kit includes a graphical user interface (GUI) that provides communication from the target device to the PC. The EV kit can operate in multiple modes: 1) Standalone Mode: In “standalone” mode, the EV kit is connected to the PC via a USB cable and performs a subset of the complete EV kit functions with limitation for sample rate, sample size, and no support for coherent sampling. 2) FPGA Mode: In “FPGA” mode, the EV kit is connected to an Avnet ZedBoard™ through a low-pin-count FMC connector. The ZedBoard features a Xilinx® Zynq® -7000 SoC, that connects to the PC through an Ethernet port, which allows the GUI to perform different operations with full control over mezzanine card functions. The EV kit with FPGA platform performs the complete suite of evaluation tests for the target IC. 3) User-Supplied SPI Mode: In addition to the USB and FMC interfaces, the EV kit provides a 12-pin PMODstyle header for user-supplied SPI interface to connect the signals for SCLKx, DINx, DOUTx, and CNVSTx. The EV kit includes Windows XP®-, Windows® 7, and Windows 8.1-compatible software for exercising the features of the IC. The EV kit GUI allows different sample sizes, adjustable sampling rates, internal or external reference options (depending upon target device selected), and graphing software that includes the FFT and histogram of the sampled signals. The ZedBoard board accepts a +12V AC-DC wall adapter. The EV kit can be powered by a local +20V supply. The EV kit has on-board transformers and digital isolators to separate the IC from the ZedBoard/on-board processor. The MAX1115X/MAX1116X EV kit comes installed with a MAX1115XEUB+/MAX1116XEUB+ in a 10-pin µMAX® package, but can also evaluate other pin-compatible parts in the family.

The Configuration tab provides control for the two ADCs configuration during data capture. The other four tabs are used for evaluating the data captured by the ADCs. In addition, the sample data can be saved to a file. The factory-default jumper settings have the ADCs on the EV kit configured for CS mode, using the Channel 1 device (U10) and Channel 2 device (U14). In the Configuration tab the correct selection must be made for CS Mode. If the busy bit is desired, select CS Mode with Busy and populate J20. Configuration Tab Daisy-Chain Mode The Configuration tab provides an interface for selecting and configuring the ADC from a functional perspective. Select the desired Device in the drop-down list and the corresponding properties of the device are displayed including Resolution, Input Range, Reference Voltage, and Max Sample Rate. If the selected ADC uses an external reference, then use the Reference Voltage numeric box to enter the measured reference value. The on-board reference is 5V. To use the ADCs in daisy-chain mode, move the shunts described in Table 3 for J19 and J38 so the SDO of U14 (DOUT2_DAISY) connects to the SDI of U10. The SDO of U10 connects to the SPI MISO for the GUI to read the data. In the Configuration tab, the correct selection must be made for Interface Mode set as Daisy-chain. The channel selection automatically changes to Both Channels in daisy-chain mode. The sampling settings are available on the left, which allow the user to select the Channel, Sample Rate, Number of Samples, and SCLK Frequency. The SCLK Frequency selection is required prior to adjusting to the desired sampling rate. There are two ADCs on the EV kit. In standalone mode, the two ADCs are read sequentially, while in FPGA mode they can be read simultaneously. To use the ADCs in multichannel mode, move the shunts described in Table 3 for CS Mode. In the Configuration tab, the correct selection must be made for Both Channels and the Interface Mode must be in CS mode. The two ADCs on the EV kit have a variety of interface modes to the master. The modes include CS mode and daisy-chain mode. Dual ADC Mode (Sequential or Simultaneous) Table 3.

Included in the EV kit are digital isolators, isolated DC-DC converters, ultra-low-noise LDOs to all supply pins of the IC, on-board references (MAX6126 and MAX6070), precision amplifiers (MAX9632 for bipolar and MAX44242 for unipolar) for analog inputs, and sync-in and sync-out signals for coherent sampling. Two ADCs are on the board to allow daisy-chain mode operation if desired. An on-board FTDI controller is provided to allow for evaluation in standalone mode, which has limitations on maximum sample speed and on sample depth. The EV kit can be used with a FPGA to achieve full speed and a larger sample depth. The EV kit supports a number of different devices with a 10-pin µMAX package as listed in Table 4. For the MAX11156 and MAX11154 in a 12-pin TDFN package, please refer to the MAX11156EVSYS# and for the MAX11166, MAX11167, MAX11164, and MAX11165 in a 12-pin TDFN package, please refer to the MAX11166EVSYS#. A full 18-bit data acquisition system featuring the MAX11156 ADC and the MAX5318 DAC is available as the MAXREFDES74# reference design, which includes an FMC interface to the FPGA and standalone USB.

FMC Interface The user should confirm compatibility of pin usage between their own FMC implementation and that of the MAX1115X/MAX1116X EV kit before connecting the MAX1115X/MAX1116X EV kit to a different system with FMC connectors. User-Supplied SPI Interface In addition to the USB and FMC interfaces, the EV kit provides a 12-pin PMOD-style header (J25) for user-supplied SPI interface. To evaluate the EV kit with a user-supplied SPI bus, disconnect from the FMC bus and remove jumper J14. Apply the user-supplied SPI signals to SCLK, CNVST, DIN, and DOUT at the PMOD header. Make sure the return ground is connected to the PMOD ground. The on-board FTDI chip used for standalone mode does not conflict with the user-supplied SPI if it is powered off by removing jumper J14. WARNING: DO NOT PLUG THIS HEADER INTO A STANDARD PMOD INTERFACE FOUND ON OTHER FPGA OR MICROCONTROLLER PRODUCTS. THE SIGNAL DEFINITION IS UNIQUE TO THIS EV KIT. Reference Depending upon the target IC on the EV kit, there are different sources for the voltage reference. As listed in Table 4, some ADCs have the option to use an internal reference. In addition, there are two voltage references on the board and the option to provide a user-supplied external reference signal. For ADCs that require an external reference, the EV kit includes two on-board references plus the option for a user-supplied reference. The MAX6126 (U11) is an ultrahigh-precision, ultra-low-noise, series voltage reference with 3ppm/°C maximum temperature coefficient and the MAX6070 (U12) low-noise, high-precision series voltage reference offers the highest performance SOT23 voltage references with 6ppm/°C maximum temperature coefficient. To use these voltage reference sources, populate jumpers J13 and J37. See Table 5 for jumper settings. For a user-supplied external reference, remove the jumper on J13 and connect a reference voltage to ADC_EXT_REF at TP12.

The MAX13256, H-bridge driver and transformer create an additional negative rail for +18V and -18V. The power is then rectified and regulated down to a +15V and -15V supplies for the MAX9632 op amps, as well +10V and -10V supplies for the MAX44242 op amps. Additional supplies are generated for +5V, +5.33V, and +3.3V/+2.5 for the ADCs and VREF. See the EV kit schematics for details. Specific voltages can be connected to the board for each rail, see Table 6 for corresponding jumper positions. Table 6.

The ADCs convert input signals on the ADC pin AIN+ (ADx_INP) in the range of (±5V + AIN-) for bipolar or (5V + AIN-) to AIN- for unipolar. For accurate conversions, the ADC pin AIN+ should also be limited to ±(VDD + 0.1V) for bipolar and (VDD + 0.1V) to -0.1V for unipolar. The ADC pin AIN- (ADx_INM) has an input range of -0.1V to +0.1V and is typically connected to the analog ground plane (AGND) of the EV kit. The MAX1115X/MAX1116X perform a true differential sample on inputs between AIN+ and AIN- with good commonmode rejection and by connecting the EV kit input signal GND_SENSE to the ground reference of the input signal source. This allows for improved sampling of remote transducer inputs. See the jumper settings in Table 2 for J34 and J39. ADC Input Amplifiers The input amplifiers allow for significant flexibility, supporting bipolar or unipolar input paths, as well as the option Evaluates: MAX11150/MAX11152/ MAX11158/MAX11160/MAX11161/MAX11162/ MAX11163/MAX11168/MAX11169 for gain control. Each ADC channel can be configured as single-ended bipolar, differential bipolar, single-ended unipolar, and differential unipolar. See Tables 8 and 9 for these analog input configurations for channels A and B, respectively. The analog front-end consists of two channels (A and B, one for each ADC) and for each channel there are four user-selectable input pairs (for example AINx+ and AINxwhere x is 0, 1, 2, or 3) allowing selection between one of two op amp solutions. The MAX9632, which is a 36V, precision, low-noise, wide-band amplifier or the MAX44242, which is a 20V, low input-bias-current, low-noise, dual op amp. The op amps can be configured as inverting or noninverting amplifiers by jumper selectors. Both op amps work as anti-aliasing lowpass filters (LPF) and can be daisy-chained to create a second-order LPF. The range of possible configurations for Channels A and B are listed in Tables 8 and 9, and the jumper connections are shown in Figures 6 to 12. Table 7.

The first ADC (U10) Common Mode (CM) bias is set with VREF1 and VREF2 depending upon the op amp selected, and the second ADC (U14) CM bias is set with VREF3 and VREF4 depending upon the op amp selected.
