NOTES:
1. All voltages are referenced to ground.
2. Resistor inputs cannot exceed V
B
- 0.5V in the negative direction.
3. INL is used to determine wiper voltage versus expected voltage as determined by wiper position.
4. DNL is used to determine the change in voltage between successive tap positions.
5. C
OUT
is active regardless of the state of
RST
.
6. See Figure 9(a), (b), and (c).
7. Supply current is dependent on clock rate (see Figure 11).
8. Standby currents apply when
RST
, DQ are in the low-state.
9. When biasing the substrate minimum V
B
= -3.0V ±10% and maximum V
CC
= 3.0V ±10%.
10. Valid at +25°C only.
