Note 2: All voltage values are with respect to ground with DGND, AGND  
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.

–5V for bipolar mode, ACLK = 2.0MHz, SCLK = 0.5MHz unless otherwise  
specified.  
Note 4: These specs apply for both unipolar and bipolar modes. In bipolar  
mode, one LSB is equal to the bipolar input span (2V ) divided by 1024.  
REF  
For example, when V = 5V, 1LSB (bipolar) = 2(5V)/1024 = 9.77mV.  
Note 5: Linearity error is specified between the actual end points of the  
A/D transfer curve.  
Note 6: Total unadjusted error includes offset, gain, linearity, multiplexer  
and hold step errors.  
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  
REF  
Note 8: Channel leakage current is measured after the channel selection.  
Note 9: To minimize errors caused by noise at the chip select input, the  
internal circuitry waits for two ACLK falling edges after a chip select falling  
edge is detected before responding to control input signals. Therefore, no  
attempt should be made to clock an address in or data out until the  
minimum chip select setup time has elapsed.
