Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No guarantee of parametric performance is indicated in the electrical tables under conditions of internal self-heating where TJ > TA. Absolute Maximum Ratings indicate junction temperature limits beyond which the device may be permanently degraded, either mechanically or electrically. (2) Register values are represented as either binary (b is the prefix to the digits), or hexadecimal (0x is the prefix to the digits). Decimal values have no prefix. (3) Limits are ensured by testing, design, or statistical analysis at 25°C. Limits over the operating temperature range are ensured through correlations using statistical quality control (SQC) method. (4) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped production material. (5) I2C read/write communication and pull-up resistors current through SCL, SDA not included. (6) Sensor capacitor: 1 layer, 20.9 x 13.9 mm, Bourns CMH322522-180KL sensor inductor with L=18µH and 33pF 1% COG/NP0 Target: Grounded aluminum plate (176 x 123 mm), Channel = Channel 0 (continuous mode) CLKIN = 40 MHz, CHx_FIN_SEL = b10, CHx_FREF_DIVIDER = b00 0000 0001 CH0_RCOUNT = 0xFFFF, SETTLECOUNT_CH0 = 0x0100, DRIVE_CURRENT_CH0 = 0x7800. (7) Lower VSENSORMIN oscillation amplitudes can be used, but will result in lower SNR. 6 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Product Folder Links: FDC2212 FDC2214 FDC2112 FDC2114 |
