Note 1:
Performance at power-supply tolerance limits guaranteed by power-supply rejection test.
Note 2:
VDD = 5V, VSS = 0V, FS = VREF.
Note 3:
FS = VREF, offset nulled, ideal last-code transition = FS - 3/2 LSB.
Note 4:
Gain-Error Tempco =
GE is the gain-error change from TA = +25°C to TMIN or TMAX.
Note 5:
Conversion time defined as the number of clock cycles times the clock period; clock has a 50% duty cycle.
Note 6:
Guaranteed by design, not production tested.
Note 7:
AIN+, AIN- must not exceed supplies for specified accuracy.
Note 8:
VREF TC =
T, where VREF is reference-voltage change from TA = +25°C to TMIN or TMAX.
Note 9:
Output current should not change during conversion. This current is in addition to the current required by the internal DAC.
Note 10: REFADJ adjustment range is defined as the allowed voltage excursion on REFADJ relative to its unadjusted value of 2.4V.
This will typically result in a 1.7 times larger change in the REF output (Figure 19a).
Note 11: This current is included in the PD supply current specification.
Note 12: Floating the PD pin guarantees external compensation mode.
Note 13: VREF = 4.096V, external reference.
Note 14: All input control signals are specified with tr = tf = 5ns (10% to 90% of 5V) and timed from a voltage level of 1.6V.
Note 15: t3 and t6 are measured with the load circuits of Figure 1 and defined as the time required for an output to cross 0.8V or 2.4V.
Note 16: t7 is defined as the time required for the data lines to change 0.5V when loaded with the circuits of Figure 2.
