CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTES:
1. Absolute linearity is utilized to determine actual wiper resistance vs expected resistance = (V_H(n)(actual) - V_H(n)(expected)) = ±1 Ml Maximum.
n = 1 .. 29 only.
2. Relative linearity is a measure of the error in step size between taps = V_H(n+1) - [V_H(n) + Ml] = ±0.5 Ml, n = 1 .. 29 only.
3. 1 Ml = Minimum Increment = R_TOT/31.
4. Typical values are for T_A = +25°C and nominal supply voltage.
5. Limits established by characterization and are not production tested.
6. When performing multiple write operations, V_CC must not decrease by more than 150mV from its initial value.
7. Parts are 100% tested at +25°C. Temperature limits established by characterization and are not production tested.
Potentiometer Characteristics Over recommended operating conditions, unless otherwise stated.
