This is a stress rating only; 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.

Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = (RH(n)(actual) - RH(n)(expected)) = ±1 Ml Maximum. n = 1 .. 29 only. 2. Relative linearity is a measure of the error in step size between taps = RH(n+1) -[RH(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. CH CL RW RTOTAL CW RH RL ISL90460 FN8225.2 June 6, 2005 |
