4 / 9 page 4 FN8188.1 March 24, 2006 ABSOLUTE MAXIMUM RATINGS Temperature under bias .................... -65 °C to +135°C Storage temperature ......................... -65°C to +150°C Voltage on CS, INC, U/D, RH, RL and VCC with respect to VSS .............................. -1V to +6.5V Lead temperature (soldering 10 seconds) ......... 300°C Maximum reflow temperature (40 seconds) ...... 240°C Maximum resistor current ..................................... 2mA COMMENT Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only; the functional operation of the device (at these or any other conditions above those listed in the operational sections of this specification) is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. POTENTIOMETER CHARACTERISTICS (Over recommended operating conditions unless otherwise stated.) Notes: (1) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = (VH(n)(actual) - VH(n)(expected)) = ±1 Ml Maximum. n = 1 .. 29 only. (2) Relative linearity is a measure of the error in step size between taps = VH(n+1) - [VH(n) + Ml] = ±0.5 Ml, n = 1 .. 29 only. (3) 1 Ml = Minimum Increment = RTOT/31. (4) Typical values are for TA = 25°C and nominal supply voltage. (5) This parameter only applies to a single potentiometer. (6) Typical parameter is guaranteed by characterization. (7) When performing multiple write operations, VCC must not decrease by more than 150mV from it’s initial value. Symbol Parameter Limits Test Conditions/Notes Min. Typ. Max.
