4 / 9 page X9312 4 ABSOLUTE MAXIMUM RATINGS* Temperature under Bias .................. –65 °C to +135°C Storage Temperature ....................... –65 °C to +150°C Voltage on CS, INC, U/D and VCC with Respect to VSS ............................... –1V to +7V Voltage on VH and VL Referenced to VSS ∆V = |VH–VL| X9312Z, X9312W, X9312U, and X9312T ....... 15V Lead Temperature (Soldering 10 seconds) ....... 300 °C Wiper Current ..................................................... ±1mA *COMMENT Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and the functional operation of the device at these or any other conditions above those listed in the operational sections of this specifica- tion is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ANALOG CHARACTERISTICS Electrical Characteristics End-to-End Resistance Tolerance ..................... ±20% Power Rating at 25 °C X9312Z, .................................................... 225mW X9312W, X9312U, and X9312T ................. 25mW Wiper Current ............................................ ±1mA Max. Typical Wiper Resistance ......................... 40 Ω at 1mA Typical Noise .......................... < –120dB/ Hz Ref: 1V Resolution Resistance ............................................................. 1% Linearity Absolute Linearity(1) ........................................ ±1.0 Ml(2) Relative Linearity(3) ..................................... ±0.2 Ml(2) Temperature Coefficient (–40 °C to +85°C) X9312W, X9312U and X9312T ....................................... +300 ppm/ °C Typical Ratiometric Temperature Coefficient ............ ±20 ppm Wiper Adjustability Unlimited Wiper Adjustment (Non-Store operation) Wiper Position Store Operations ............... 10,000 Data Changes Physical Characteristics Marking Includes Manufacturer’s Trademark Resistance Value or Code Date Code Test Circuit #1 Test Circuit #2 3865 FHD F04 3865 FHD F05 FORCE CURRENT VL VW VH TEST POINT TEST POINT VW VH VL Notes: (1) Absolute Linearity is utilized to determine actual wiper voltage versus expected voltage = (Vw(n)(actual) – Vw(n)(expected)) = ±1 Ml Maximum. (2) 1 Ml = Minimum Increment = RTOT/99. (3) Relative Linearity is a measure of the error in step size between taps = VW(n+1) – [Vw(n) + Ml] = +0.2 Ml. |
