6. A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the V
IHMIN
of the
SCL signal) in order to bridge the undefined region of the falling edge of SCL.
7. The maximum t
HD:DAT
has only to be met if the device does not stretch the LOW period (t
LOW
) of the SCL signal.
8. A fast mode device can be used in a standard mode system, but the requirement t
SU:DAT
> 250 ns must then be
met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such
a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line t
RMAX
+ t
SU:DAT
= 1000 + 250=1250 ns before the SCL line is released.
9. C
B
– total capacitance of one bus line in picofarads, timing referenced to (0.9)(V
CC
) and (0.1)(V
CC
).
10.Typical values are for t
A
= 25
°
C and nominal supply voltage.
11. –3 dB cutoff frequency characteristics for the DS1803 depend on potentiometer total resistance: DS1803–010;
1 MHz, DS1803–50; 200 KHz, DS1803–100; 100 KHz.
12.Address Inputs, A0, A1, and A2, should be tied to either V
CC
or GND depending on the desired address selections.
13.Absolute linearity is used to determine wiper voltage versus expected voltage as determined by wiper position.
Device test limits are
±
1.6 LSB.
14.Relative linearity is used to determine the change in voltage between successive tap positions. Device test limits
±
0.5 LSB.
15.Fast mode.
16.Standard mode.
