DYNAMIC CHARACTERISTICS

18. The ADCs use a Sinc

filter for the 3200 Sps and 3840 Sps output word rate (OWR) and a Sinc

filter

followed by a Sinc

filter for the other OWRs. OWR

sinc5

refers to the 3200 Sps (FRS = 1) or 3840 Sps

(FRS = 0) word rate associated with the Sinc

filter.

19. The single conversion mode only outputs fully settled conversions. See Table 1 for more details about

single conversion mode timing. OWR

is used here to designate the different conversion time

associated with single conversions.

20. The continuous conversion mode outputs every conversion. This means that the filter’s settling time

with a full scale step input in the continuous conversion mode is dictated by the OWR.

ABSOLUTE MAXIMUM RATINGS

(DGND = 0 V; See Note 21.)

Notes: 21. All voltages with respect to ground.

22. VA+ and VA- must satisfy {(VA+) - (VA-)} ≤ +6.6 V.

23. VD+ and VA- must satisfy {(VD+) - (VA-)} ≤ +7.5 V.

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

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

supply pin is ±50 mA.

26. 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.
