Default current is set to 20mA (refer to the MAX1366 data sheet for current settings). Evaluate MAX1366/MAX1368 microcontroller-interfaced LED drivers (see Table 2 for evaluating other devices) *Default position. Note 1: The MAX1366/MAX1368 expects a 6.2k (typ) source impedance from the voltage source driving CONV_IN (normally driven by the on-chip DAC). Note 2: The purpose of R1 is only for quick voltage measurement. The R1 tolerance determines the current-to-voltage transfer function. Note 3: The current output accuracy of the device is maintained over the range of 0V to 2.5V. To interface with a high-loop voltage, such as 7V to 30V, a user may use the current output to drive an external current mirror. The external current mirror may significantly degrade 4-20mA current-output offset, gain, and associated temperature coefficients. See Detailed Description of Hardware section for details. Figure 1. MAX1366 Evaluation Software--Control Register Tab Detailed Description of Software To start the MAX1366 EV kit software, double-click the MAX1366 EV kit icon created during installation. The GUI window appears, as shown in Figure 1. Wait approximately two seconds while the MAX1366 EV kit software connects to the CMAXQUSB board. 4 On the lower half of the software window, the user can monitor the activity details of the SPI interface if one single SPI transaction is executed. If more than one SPI read or write commands are sent, only the last transaction details are displayed on the GUI window. _______________________________________________________________________________________ MAX1366 Evaluation Kit/Evaluation System Control Register The Control Register tab shown in Figure 1 contains the primary control register for the MAX1366. Set or clear any bit in this register by choosing the appropriate dropdown menu. Voltage Measurement The Voltage Measurement tab shown in Figure 2 mimics the behavior of a digital voltmeter (DVM). The status bits are checked and displayed every time a sample is collected, either by manually clicking the Collect Sample button, or automatically by the software if the Auto Collect checkbox is enabled. The Result Registers 1 & 2 Code displays the 20-bit result register (combination of result register 1 and result register 2 in two's complement code) in decimal format. The Voltage (mV) displays the calculated input voltage based on the result-register values and the value entered into EXT REF Voltage(V) field. Compare the voltage source reading against the LED reading to check the conversion accuracy. The EV kit is a 2V range DVM, outside this range inputscaling and protection circuitry is recommended. Whenever the Voltage Measurement tab is activated, the software clears the SPI/ADC and SEG_SEL control bits to zero if they are not already cleared. Figure 2. MAX1366 Evaluation Software--Voltage Measurement Tab _______________________________________________________________________________________ 5 Evaluate: MAX1365-MAX1368 There are seven tab pages on the software window. These pages let the user configure and test different features of the MAX1366. They are the Control Register, Voltage Measurement, Results, Display, Limits, LED Segments, DAC, Current Output, Register Watch, and Math tabs. Evaluate: MAX1365-MAX1368 MAX1366 Evaluation Kit/Evaluation System Results, Display, Limits The Results, Display, Limits tab shown in Figure 3 provides access to the two's complement data registers. Each register has Read and Write buttons, except for ADC RESULT 1, ADC RESULT 2, and PEAK RESULT, which are read-only. The reading or writing to the LED DATA register depends on the setting of the SPI/ADC bit. All the fields are shown in both decimal and hexadecimal formats. Whenever a writable field is changed, the font color is changed to red. This reminds the user that the new data has not been written to the device. Figure 3. MAX1366 Evaluation Software--Results, Display, Limits Tab 6 _______________________________________________________________________________________ MAX1366 Evaluation Kit/Evaluation System The user can read all the LED register values by clicking the appropriate buttons (Read LED Segment Reg 1, Read LED Segment Reg 2, Read LED Segment Reg 3, or Read all). The user can also set all segments on by clicking the All Segments On button and set all segments off by clicking the All Segments Off button. Figure 4. MAX1366 Evaluation Software--LED Segments Tab _______________________________________________________________________________________ 7 Evaluate: MAX1365-MAX1368 LED Segments The LED Segments tab shown in Figure 4 lets the user turn individual LED segments on and off by clicking them with the mouse. Whenever the LED Segments tab is activated, the software sets the SEG_SEL control bit to one if it is not already set. Evaluate: MAX1365-MAX1368 MAX1366 Evaluation Kit/Evaluation System DAC, Current Output The DAC, Current Output tab shown in Figure 5 lets the user configure the DAC and V/I converter. After selecting one output mode, the user can check the ideal output current by clicking the Ideal Output Current button. This checks the accuracy of the output by comparing the ideal output reading on the GUI and the reading on the current meter. When selecting the DAC input to follow the DAC register value, the user should click the Write button to write the new typed value to the device. Figure 5. MAX1366 Evaluation Software--DAC, Current Output Tab 8 _______________________________________________________________________________________ MAX1366 Evaluation Kit/Evaluation System Evaluate: MAX1365-MAX1368 Register Watch The Register Watch tab shown in Figure 6 contains all of the twelve registers of the MAX1366. The user can directly read all the current values of the registers. Figure 6. MAX1366 Evaluation Software--Register Watch Tab _______________________________________________________________________________________ 9 Evaluate: MAX1365-MAX1368 MAX1366 Evaluation Kit/Evaluation System Math The Math tab shown in Figure 7 implements several math functions found in physical systems. Whenever the Math tab is activated, the software sets the SPI/ADC control bit to 1 if it is not already set. The software also clears the SEG_SEL control bit to zero if it is not already cleared. The evaluation software intercepts the ADC result and displays it on the ADC Result Code panel. This is the same as on the Voltage Measurement tab page. It then calculates a new value without considering the digits limit of the LED display and displays it on the Calculated Result panel. Finally, the software shows the calculated result on the LED with the closest approximation and automatically sets the decimal-point position. The Type K Thermocouple function can be used along with a suitable cold-junction connection to convert a type K thermocouple's measured Seebeck voltage into temperature in degrees centigrade. The a0 coefficient 23 represents a cold-junction temperature of 23C (the output depends on the sensitivity of the thermocouple). Figure 7. MAX1366 Evaluation Software--Math Tab 10 ______________________________________________________________________________________ MAX1366 Evaluation Kit/Evaluation System The MAX1366 (U1) is a low-power, 4.5-digit ADC with integrated LED drivers and 4-20mA output. The MAX6126 (U2) provides an on-board +2.048V reference voltage. See Figure 9 and refer to the MAX1366 data sheet for more information. Evaluating the MAX1365/MAX1367/MAX1368 The MAX1366 EV kit supports the MAX1368 3.5-digit panel meter with LED drivers and 4-20mA output. All the features can be tested using the same software. The MAX1366 EV kit also supports the MAX1365/ MAX1367 stand-alone digital panel meters with LED drivers. However, the evaluation software is not needed because there is no microprocessor interface on the MAX1365/MAX1367, but the stand-alone devices can be evaluated by configuring the on-board SW1 and SW2 DIP switches. See Tables 1 and 2 for detailed configuration of jumpers and DIP switches for evaluating the MAX1365, MAX1367, and MAX1368. Request a free sample of the MAX1365, MAX1367, or MAX1368 to test their features. Power Supplies The DVDD, AVDD, and DAC_VDD can use the power supply from the interface board for simple connection. Selections are 3.3V and 5V. For other valid supply voltages, the user can apply power supplies on the DVDD, AVDD, and DAC_VDD pads, respectively. Regulator/reference buffer power should be connected through J1, position 3. The input range is 4.75V to 5.25V. Current-loop power should be connected through terminal block J1 position 2. The input range is 7V to 30V. LED power supply should be connected on VLED and LEDG pads (see the IC data sheet for absolute maximum ratings). Table 2.

The MAX1366 DAC_VOUT pin is connected directly to the CONV_IN pin to have the current output (4-20mA or 0 to 16mA) follow the analog inputs. The board offers a choice to use the current output as either a current source or a current sink. See Figure 8 for a simple current mirror. If used as a current source, JU8 pins 1-2 should be connected. If used as a current sink, JU8 pins 2-3 should be connected. The current-output accuracy of the device is maintained over the range of 0V to 2.5V. The external current mirror may significantly degrade 4-20mA current output offset, gain, and associated temperature coefficients. The user is responsible for constructing a more precise current mirror if high accuracy of the device is to be maintained. The on-board current mirror is shown for demonstration purpose only. 12 4-20 SOURCE 4-20OUT 4-20 SINK 4-20OUT RLOAD N RLOAD R10 Figure 8.
