evaluate: max1304?ax1315 max1308 evaluation kit/evaluation system 4 _______________________________________________________________________________________ detailed description of software to start the software, double-click the max1308 ev kiticon that is created during installation. the serial form, shown in figure 1, appears and the user must click ok to upload the firmware to the 68hc16mod-16wideand begin the program. when the firmware has been uploaded and the ? on the 68hc16mod-16wide has booted, the max1308 evaluation software (shown in figure 2) appears. the part pulldown menu allows the user to select any part in the max1304ecm?ax1315ecm family. bydefault, the max1308ecm is selected. the sampling pulldown menu allows the user to select between threesampling modes: single sample, continuous sample, and block sample. note that in block-sample mode, the user can select the sampling rate (per channel) and this rate changes depending on how many channels are selected. the check boxes in the power saving modes box allow the user to enable the different power-saving fea-tures of the max1308. the two check boxes are labeled shdn pin and /chshdn pin and represent the state of the max1308? pin with the same designation. checking and unchecking these boxes sets the corre- sponding ic pin high and low, respectively. the channel select box contains a check box for each input channel of the ic. checking the box allows thesoftware to sample the channel. the input values box displays the raw data and corre- sponding input voltage of all selected channels aftersampling. the references box allows the user to specify the exact references being used. the values for the refer-ence voltage and the midscale voltage should be entered here. these values are used in the transfer function for converting the raw data into a correspond- ing input voltage. the sample options box is used to control sampling in any of the three sampling modes. in single-sample mode,the sample button is used to sample all selected chan- nels once. in continuous-sample mode, the start and stop buttons are used to sample all selected channels and a sampling interval (between 200ms and 10,000ms)can be entered in the sampling interval text field. in block-sample mode, the sample button is used to bring up the sampling tool (see figure 3) and the sampling frequency scrollbar is used to select a sampling fre- quency per channel. note that the sampling frequency is adjusted as channels are selected/unselected and is typi-cally accurate to within 0.5ms. to determine the exact sampling frequency per channel in block-sample mode, observe consecutive falling edges on the convst pin (j1-7) when sampling. to capture data for precision ffts, use the max1308 ev kit with an external clock and a logic analyzer (instead of the 68hc16mod-16 wide) to read the parallel bus. this improves the accuracy of the adc clocking system. when using the max1308 evaluation software, it can be useful to display the serial form and/or graph form. to display these forms, click on the appropriate command in the options menu. the serial form displays all com- munication between the max1308 evaluation softwareand the 68hc16mod-16wide. the graph form (see figure 4) displays a graph of sampled results when the software is in continuous-sample mode. note that when viewing graphical information (using either the graph form in continuous-sample mode or done automatically in block-sample mode), the raw codes collected from the max1308 are converted from two? complement (or offset binary in unipolar devices) to signed decimal. the raw data can be saved to a text file using the save menu item in the graph window. detailed description of hardware MAX1308EVB16 ev system the MAX1308EVB16 is a complete 8-channel, 12-bit,data-acquisition system consisting of a max1308 ev kit and the maxim 68hc16mod-16wide ? module. 68hc16mod-16wide ? module the 68hc16mod-16wide provides a 16-bit parallelbus to demonstrate various maxim devices. maxim reserves the right to change the implementation of this module at any time with no advance notice. max1308 ev kit the max1308 ev kit board provides a proven layout forevaluating the max1308 8-channel, 12-bit adc and can be obtained separately without the 68hc16mod-16wide ? module. the max1308 ev kit includes an on-board 2.5v reference (max6126) and buffers (max4351) for all eight input channels. the max1308ecm (u1) is powered from two sources. the user must supply +5v between avdd and agnd, and +3v to +5v between dvdd anddgnd. dvdd can also be supplied from the 68hc16mod-16wide using ju15. downloaded from: http:///

evaluate: max1304?ax1315 max1308 evaluation kit/evaluation system _______________________________________________________________________________________ 7 the input buffers require a +5.5v positive supply(hvavcc) and a -5.5v negative supply (hvavee). the positive supply for the input buffers must be applied on the hvavcc pad or connected to avdd using ju16. the negative supply must be applied on the hvavee pad. connect the ground for these supplies to the agnd pad. jumpers on the ev kit allow evaluation of all the parts in the max1304?ax1315 family. when changing between parts in the family, ju1 and ju13 must be set according to whether the ic accepts bipolar or unipolar inputs. if the ic has less than eight input channels (i.e., four channels or two channels), the unused input pins can be connected to agnd or left floating. note that if the inputs are buffered and exceed ?v (i.e., when using the max1312?ax1315 that support inputs up to ?0v), replace the max4351 buffers (u2?5) with buffers capable of ?0v voltage range. the max1308 on the ev kit uses the on-board max6126 2.5v reference instead of its internal refer- ence when shipped. to use the max1308? internal 2.5v reference, remove the shunt from ju2. the user can also use an external reference by first removing the shunt from ju2 and applying the reference voltage to the ref pad. when using a non-default reference value, the user must update the value in the ev kit soft- ware? references box. a logic analyzer can be used instead of the68hc16mod-16wide to evaluate the max1308 ev kit. for this configuration, disconnect the ev kit from the 68hc16mod-16wide and connect the logic analyzer to j1 and j2. these headers allow access to the max1308 control (j1) and data (j2) pins. when shipped, the max1308 ev kit is set to use the max1308 internal clock, but an external clock can be supported. to use an external clock, connect the clock signal to the eclk sma connector, remove the shunt from ju4, and set the shunt on ju14 to the 2-3 position. in this configuration, the 68hc16mod-16wide can no longer be used and the user must supply a parallel interface (i.e., a logic analyzer). when not using the 68hc16mod-16wide as the paral- lel interface, the max1308 ev kit can be put into autoread mode by placing a jumper on pins 1-2 of ju3. in this mode, the max1308 eoc pin is connected to the rd strobe and available samples are immediately outputted on the parallel bus. when performing autoread, the cs pin can be connected low by placing a jumper between j1-9 and j1-10.note that when the 68hc16mod-16wide is not being used as the parallel interface, ju15 must be set to the 1-2 position and dvdd must be supplied between thedvdd and dgnd pads on the ev kit. jumper selection tables the following tables (tables 1?) explain the functional-ity of each jumper on the max1308 ev kit. jumper shunt position description short* select internal clock as adcsystem clock. ju4 open select external eclk sma as adc system clock. table 4. adc clock-source select * default configuration. jumper shunt position description short* midscale voltage is set for bipolarinputs. ju1 open midscale voltage is set for unipolarinputs. table 1. midscale voltage select * default configuration. jumper shunt position description short* select on-board 2.5v reference(max6126) as voltage reference. ju2 open select i nter nal 2.5v r efer ence or exter nal re f p ad as vol tag e r efer ence. n ote that exter nal r efer ence m ust b e b etw een 2v and 3v . table 2. reference select * default configuration. jumper shunt position description short connects rd and eoc lines for autoread mode. ju3 open* disables autoread mode. table 3. autoread mode * default configuration. downloaded from: http:///
