The "Configuration" page provides an easy-to-use tool for updating the device configuration and provides additional information about how the device will perform. 2.7.1 Enabling and Disabling Channel Measurements The FDC211x and FDC221x devices take measurements in two different modes: repeated single channel measurement and measuring single channels sequentially. When the device repeatedly measures a single channel any channel can be selected for measurement. To measure a single channel follow these steps. 1. Select “Repeat single channel measurement” in the “Measurement Settings” 2. Choose which channel to measure by clicking the enable check-box of the desired channel (any channel may be selected) If measuring more than one channel, they are always measured sequentially from channel 0 to the highest selected channel. To measure multiple channels follow these steps. 1. Select “Sequence channel measurements” in the “Measurement Settings” 2. Choose which channels to measure by clicking the highest channel desired Channel 0 and 1 will always be enabled in this mode 2.7.2 Selecting the Clocking Source While the device contains an internal oscillator which requires fewer components in a system, it is recommended to use an external oscillator for precision applications. The EVM includes a 40MHz oscillator on-board, but an external off board signal can be used. To choose the oscillator source select one of the options in the “Reference Clock Source” section of the “Measurement Settings”. If using an external oscillator, enter the oscillation frequency so that the GUI correctly displays data measurements of frequency and capacitance. Please note changing the value of the clock in the GUI is purely for calculations in the GUI, the actualy clock frequency on the EVM will not change. 2.7.3 Setting the Measurement Timings Determining the best timing settings for the device is largely dependent on the application and sensor design, but in general the following items should be considered • Each channel should have the maximum reference frequency possible. Most applications should have the channel Fref dividers set to one. • Settle count needs to be long enough, but increasing it arbitrary holds no value and only decreases the sampling rate. Reference the datasheet for calculating the optimal settle count. • Reference count has the largest effect on the accuracy of a measurement. Increasing the reference count leads to a more accurate measurement, but at the cost of decreased sampling rate. The effective number of bits for each channel is calculated in the table for each channel based on the reference count.

The sensor’s resonant frequency could be vastly different or a different sensor inductor could be used. If the resonant frequency of the sensor is less than 8.75MHz the Fin select should be set to one. If the sensor frequency is greater than 8.75 MHz, Fin select should be two. The sensor filter inductor for each channel should be updated to reflect to actual component value on the sensor. Figure 25. Sensor Properties and Input Adjustments on Configuration Page While the FDC2214 doesn't support any gain or offset adjustments, the FDC2114 device has a limited measurement resolution and so a gain or offset may need to be set. The code offset may be set in the “Sensor Properties and Input Adjustments” table and the input gain is globally set for all channels. Please reference the device datasheet for more information to correctly set these values. 2.7.5 Setting the Input Deglitch Filter The input deglitch filter suppresses EMI and ringing above the sensor frequency. It does not impact the conversion result as long as its bandwidth is configured to be above the maximum sensor frequency. After the sensor frequency is determined, select the lowest setting which exceeds the sensor frequency.

When low power sensor activation mode is enabled, the IDRIVE code determines how much current the device supplies to the sensor. To determine the optimal current drive setting, move the system target to its furthest distance from the sensor and click the “Detect iDriveInit with Auto-Amplitude Correction” button. This will take a measurement to determine an appropriate current setting. After the setting has been measured, the code value of Idrive must be adjusted. If the low power sensor activation mode is disabled, the Idrive settings are ignored. If only measuring channel 0 and the sensor requires maximum drive current, enable the high current sensor drive.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
