Refer to the MAX11200/MAX11210, MAX11203/MAX11213, MAX11206/MAX11207, and MAX11209/MAX11211 IC data sheets for calibration details. The following calibration procedure details how to use all the calibration registers in a measurement. 1) 2) e. 3) Press the Send button. The device performs a system offset calibration with self-calibration registers enabled. The second step of the system calibration is to perform a system gain calibration. The SOC register must be enabled before a system gain calibration is performed. a. This is a conversion with the inputs held at system full-scale reference. For the EV kit, one option is to place the shunt on JU9 across pins 1-2 (AINP = REFP = 3.0V) and place the shunt on JU8 across pins 3-4 (AINN = REFN = GND). In the case of a user system, the user should apply the target system full-scale reference to the AINP and AINN inputs. To perform a self-calibration (both offset and gain): a. This is a conversion with internally shorted inputs, which is done by the internal state machine. No user manual action is required. That is, JU9 and JU8 shunt positions can be anywhere. b. In the CAL1, CAL0 group box, select the 01 - Self Calibration radio button. b. c. In the IMPD group box, select 0 - Calibration/Conversion radio button. the In the CAL1, CAL0 group box, select the 11 - System Gain Calibration radio button. c. d. Press the Send button. The device performs a self-calibration. In the IMPD group box, select 0 - Calibration/Conversion radio button. d. In the CTRL3 register row, type 10 in the Write Value edit box to enable the system offset register and the self-calibration registers. Press the Write button. e. Press the Send button. The device performs a system gain calibration. To perform a system calibration, a system offset calibration must be performed first: a. This is a conversion with the inputs held at system zero. For the EV kit, one option is to place the shunt on JU9 across pins 7-8 (AINP = GND) and place the shunt on JU8 across pins 7-8 (AINN = GND). In the case of a user system, the user should apply the target system zero to the AINN and AINP inputs. b. In the CAL1, CAL0 group box, select the 10 - System Offset Calibration radio button. c. In the IMPD group box, select 0 - Calibration/Conversion radio button. d. In the CTRL3 register row, type 18 in the Write Value edit box to enable SCOC and SCGC registers. Press the Write button. the 4) To enable the calibration coefficients: a. 5) the In the CTRL3 register row, type 00 in the Write Value edit box. Press the Write button. All the self and system calibration gain and offset values are used in the calculation of the conversion result. Continue to perform a measurement by connecting AINP and AINN to the measurement target. Programmable Gain Register Bits In the CTRL3 register of the MAX11206, MAX11209, MAX11210, and MAX11213 devices, there are 3 digital gain bits that control the input-referred gain.

Select the expected bit values and press the Send button to send the command to the ADC. In the middle section of the main window, SPI register access commands can be generated. On each register row, the register bit names are listed. Press the Read button to read the register value. Type in a new value in the Write Value edit box, and press the Write button to write a new value to the register. Every write operation is automatically followed by a readback operation to verify that the write operation is successful. Press the Read All button to read all the register values. Press the Write All button to write all the new values in the edit boxes to the registers. type in the new values, and press Enter to update these values for conversion-result calculation. In the Number of Samples Requested edit box, type in the number of samples expected. Press the Start Conversion & Data Logging button to start a data-acquisition session. For continuous conversion mode, the user can discard the first 3 samples by checking the Do not log the first 3 samples checkbox. Press the Stop Conversion & Data Logging button to stop the data-acquisition session before the requested number of samples is reached. After a data-acquisition session is complete or stopped by the user, the software displays a popup window (Figure 4) asking if the user wants to save the data to a file. If the user presses the Yes button, the software displays a Save As window (Figure 5) to let the user input the file information for logged data. In the bottom section of the main window, EV kit and device status are displayed. The CLK Selection group box lists the clock input options for the MAX11200 family of data converters. The Conversion Mode group box is a duplicate for the SCYCLE register bit. In the REFP, REFN, AVDD group box, the factory-set AVDD and reference voltages are listed. The user can apply user-supplied AVDD and reference voltages, Figure 4.

The EV kits provide on-board isolated power supplies and optocouplers to reduce noise. The EV kits can do simple real-time data acquisition for the user to evaluate the performance of the devices. See Table 3 for a description of all EV kit jumper configurations. Signal Routing When using an external reference, firmly connect the reference cables on pins 9 and 10 of the J1 connector. The devices in the MAX11200 family are single-channel data converters. Normally, the inputs are applied on pins 11 and 12 of the J1 connector. Using GPIO1, GPIO2, and GPIO3 to control the MAX4782 4-channel multiplexer, 4 channels of signals can be input to the MAX11200 family devices. See Table 4 for GPIO1, GPIO2, and GPIO3 functions.
