AC ELECTRICAL CHARACTERISTICS
(VCC = 3.0V to 5.5V, TA = -40°C to +95°C, unless otherwise noted.)
Note 1:
All voltages are referenced to ground.
Note 2:
I/O pins of fast-mode devices must not obstruct the SDA and SCL lines if VCC is switched off.
Note 3:
SDA and SCL are connected to VCC and all other input signals are connected to well-defined logic levels.
Note 4:
The maximum voltage the MON inputs will read is approximately 2.5V, even if the voltage on the inputs are
greater than 2.5V.
Note 5:
This voltage is defining the maximum range of the analog-to-digital converter and not the maximum
VCC voltage.
Note 6:
Absolute linearity is the difference of measured value from expected value at DAC position. The expected value is a
straight line from measured minimum position to measured maximum position.
Note 7:
Relative linearity is the deviation of an LSB DAC setting change vs. the expected LSB change. The expected LSB change
is the slope of the straight line from measured minimum position to measured maximum position.
Note 8:
See the Typical Operating Characteristics.
Note 9:
A fast-mode device can be used in a standard-mode system, but the requirement tSU:DAT > 250ns must then be met. This
is automatically 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 tRMAX + tSU:DAT = 1000ns + 250ns = 1250ns
before the SCL line is released.
