23. VD+ must always be less than (VA+)+0.3 V,and can never exceed 6.0V.
24. Applies to all pins including continuous overvoltage conditions at the analog input (AIN) pin.
25. Transient currents of up to 100mA will not cause SCR latch-up. Maximum input current for a power
corresponding reduction in noise-free resolution. The common mode voltage of the voltage reference
may be any value as long as +VREF and -VREF remain inside the supply values of VA+ and VA-.
mode the CS5505/6/7/8 will output all 1’s if the dc input magnitude ((AIN+)-(AIN-)) exceeds
((VREF+)-(VREF-)) and will output all 0’s if the input becomes more negative than 0 Volts.
In bipolar mode the CS5505/6/7/8 will output all 1’s if the dc input magnitude ((AIN+)-(AIN-)) exceeds
((VREF+)-(VREF-)) and will output all 0’s if the input becomes more negative in magnitude than
-((VREF+)-(VREF-)).
