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-)).

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. CS5504 DS126F1 9 CS5504 DS126F2 9 |
