DS1867
12 of 14
102199
NOTES:
1.
All voltages are referenced to ground.
2.
Resistor inputs cannot exceed the substrate bias voltage, V
B
, 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 t
A
=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.
C
OUT
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 V
CC
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.
t
REC
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.
