CS5509
DS125F3 9
Notes: 19. All voltages with respect to ground.
20. The CS5509 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 GND.
Notes: 21. No pin should go more positive than (VA+) + 0.3 V.
22. VD+ must always be less than (VA+) + 0.3 V, 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 100 mA 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.
