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 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. Limits established by characterization and are not production tested.
6. When performing multiple write operations, VCC must not decrease by more than 150mV from its initial value.
7. Parts are 100% tested at +25°C. Over-temperature limits established by characterization and are not production tested.
Potentiometer Specifications Over recommended operating conditions, unless otherwise stated.
