Typical values: T
A
= 25°C and 3.0 V
All min/max limits are guaranteed by ISD via electrical testing or characterization. Not all specifications are 100
percent tested.
Low-frequency cut off depends upon the value of external capacitors (see Pin Descriptions).
Single-ended input mode. In the differential input mode, V
IN
maximum for ANA IN+ and ANA IN– is 16 mVp-p.
Sampling Frequency can vary as much as ± 2.25 percent over the commercial temperature, and voltage ranges,
and –6/+ 4 percent over the extended temperature, industrial temperature and voltage ranges. For greater
stability, an external clock can be utilized (see Pin Descriptions).
Playback and Record Duration can vary as much as ± 2.25 percent over the commercial temperature and voltage
ranges, and –6/+ 4 percent over the extended temperature, industrial temperature and voltage ranges. For
greater stability, an external clock can be utilized (see Pin Descriptions).
Filter specification applies to the anti-aliasing filter and the smoothing filter. Therefore, from input to output, expect
a 6dB drop by nature of passing through both filters.
The typical output voltage will be approximately 570 mVp-p with V
IN
at 32 mVp-p.
For optimal signal quality, this maximum limit is recommended.
