NOTES:
1. All voltages are referenced to ground.
2. Resistor inputs cannot exceed the substrate bias voltage, VB, in the negative direction.
3. Capacitance values apply at 25
°C.
4. Absolute linearity is used to determine wiper voltage versus expected voltage as determined by wiper
position. Test limits for absolute linearity are
±1.6 LSB.
5. Relative linearity is used to determine the change in voltage between successive tap positions. Test
limits for relative linearity are
±0.5 LSB.
6. Typical values are for tA =25
°C and nominal supply voltage.
7. -3 dB cutoff frequency characteristics for the DS1867 depend on potentiometer total resistance:
DS1867-010; 1 MHz, DS1867-050; 200 kHz, DS1867-100; 100 kHz.
8. COUT is active regardless of the state of RST .
9. Power-down time is specified at a minimum of 4 ms. It is the time required for the DS1867 to
guarantee wiper position storage as VCC moves from 4.5V to 3.0V.
10. This is the time from power trip-point min (3.9V) to 3.0V to guarantee wiper storage.
11. tREC is the time required before the DS1867 stored wiper position becomes valid on power-up.
12. Power trip points reference required voltage necessary for DS1867 to restore the stored wiper position
setting.
13. See Figure 11.
14. During power-up the wiper position will be set at 80H.
15. See Figure 2.
16. A device write is specified as being a controlled power-down providing enough time to complete an
EEPROM write. It is also defined as a complete bit change from one value to another, i.e., 0 to 1.
Power-downs which do not change the wiper value can be expected have 200,000-write durability.
17. Valid at 25
°C only.
