Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: All voltage values are with respect to DGND, AGND and REF
鈥� wired
together (unless otherwise noted).
Note 3: VCC = 5V, VREF+ = 5V, VREF鈥� = 0V, V
鈥� = 0V for unipolar mode and
鈥�5V for bipolar mode, CLK = 1.0MHz unless otherwise specified. The
鈼�
denotes specifications which apply over the full operating temperature
range; all other limits and typicals TA = 25
掳C.
Note 4: These specs apply for both unipolar and bipolar modes. In bipolar
mode, one LSB is equal to the bipolar input span (2VREF) divided by 4096.
For example, when VREF = 5V, 1LSB (bipolar) = 2 (5V)/4096 = 2.44mV.
Note 5: Linearity error is specified between the actual end points of the A/
D transfer curve. The deviation is measured from the center of the
quantization band.
Note 6: Recommended operating conditions.
Note 7: Two on-chip diodes are tied to each reference and analog input
which will conduct for reference or analog input voltages one diode drop
below V
鈥� or one diode drop above VCC. Be careful during testing at low
VCC levels (4.5V), as high level reference or analog inputs (5V) can cause
this input diode to conduct, especially at elevated temperatures, and cause
errors for inputs near full scale. This spec allows 50mV forward bias of
either diode. This means that as long as the reference or analog input
does not exceed the supply voltage by more than 50mV, the output code
will be correct. To achieve an absolute 0V to 5V input voltage range will
therefore require a minimum supply voltage of 4.950V over initial
tolerance, temperature variations and loading.
Note 8: Channel leakage current is measured after the channel selection.
