NOTES
1
Operating temperature range is as follows: B Version: –40
°
C to +85
°
C.
2
f
is the CLKIN frequency.
3
See Terminology section.
4
F
= output data rate.
5
When using the internal reference, THD and SFDR specifications apply only to input signals above 10 kHz with a 10
μ
F decoupling capacitor between REF2 and
AGND2. At frequencies below 10 kHz, THD degrades to –80 dB and SFDR degrades to –83 dB.
6
See Figures 23 and 24 for information regarding the number of filter taps allowed and the current consumption as the CLKIN frequency is varied.
7
The AD7725 can operate with an external reference input in the range of 1.2 V to 3.15 V.
8
Guaranteed by the design.
9
Gain Error excludes reference error.
10
All I
tests are done with the digital inputs equal to 0 V or DV
.
11
Analog current does not vary as the CLKIN frequency and the number of filter taps used in the postprocessor is varied.
12
If HALF_PWR is logic low, AI
will typically double.
13
Digital current varies as the CLKIN frequency and the number of filter taps used in the postprocessor is varied. See Figures 23 and 24.
14
Digital inputs static and equal to 0 V or DV
