Integral Nonlinearity
VCC = VREF+ = 5V
Integral Nonlinearity
VCC = 5V, VREF+ = 3V
Integral Nonlinearity
VCC = VREF+ = 3V
The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. (Notes 2, 7)
I2C TIMING CHARACTERISTICS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2. All voltage values are with respect to GND. VCC = 2.7V to 5.5V,
unless otherwise specified. Specifications apply to both 30Hz and 60Hz
modes unless otherwise specified.
VREF = VREF+ – VREF–, VREFCM = (VREF+ + VREF–)/2, FS = VREF+ – VREF–;
VREF– ≤ VIN ≤ VREF+
Note 3. Guaranteed by design, not subject to test.
Note 4. Integral nonlinearity is defined as the deviation of a code from
a straight line passing through the actual endpoints of the transfer
curve. The deviation is measured from the center of the quantization
band. Guaranteed by design, test correlation and 3-point transfer curve
measurement.
Note 5. Input sampling current is the average input current drawn from
the input sampling network while the LTC2451 is actively sampling the
input. CB = capacitance of one bus line in pF.
Note 6. CB = capacitance of one bus line in pF.
Note 7. All values refer to VIH(MIN) and VIL(MAX) levels.
Note 8. A positive current is flowing into the DUT pin.
