DYNAMIC CHARACTERISTICS
12. The ADCs use a Sinc
5
filter for the 3200 Sps and 3840 Sps output word rate (OWR) and a Sinc
5
filter
followed by a Sinc
3
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
5
filter.
13. The single conversion mode only outputs fully settled conversions. See Table 1 for more details about
single conversion mode timing. OWR
SC
is used here to designate the different conversion time
associated with single conversions.
14. 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 15.)
Notes: 15. All voltages with respect to ground.
16. VA+ and VA- must satisfy {(VA+) - (VA-)} ≤ +6.6 V.
17. VD+ and VA- must satisfy {(VD+) - (VA-)}
≤ +7.5 V.
18. Applies to all pins including continuous overvoltage conditions at the analog input (AIN) pins.
19. Transient current of up to 100 mA will not cause SCR latch-up. Maximum input current for a power
supply pin is ±50 mA.
20. 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.
