Notes: 18. All voltages with respect to ground.

19. The CS5504 can be operated with a reference voltage as low as 100 mV; but with a

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-.

20. The CS5504 can accept input voltages up to the analog supplies (VA+ and VA-). In unipolar mode

the CS5504 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 CS5504

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-)).

Notes: 21. No pin should go more positive than (VA+)+0.3V.

22. VD+ must always be less than (VA+) +0.3V, and can never exceed +6.0 V.

23. Applies to all pins including continuous overvoltage conditions at the analog input (AIN) pin.

24. Transient currents of up to 100mA will not cause SCR latch-up. Maximum input current for a power

supply pin is

± 50 mA.

25. Total power dissipation, including all input currents and output currents.

* WARNING: Operation at or beyond these limits may result in permanent damage to the device.

Normal operation is not guaranteed at these extremes.
