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 16mVp-p.
For greater stability, an external clock can be utilized (see Pin Descriptions).
Filter specification applies to the antialiasing 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 570mVp-p with V
IN
at 32mVp-p.
For optimal signal quality, this maximum limit is recommended.
When a record command is sent, T
RAC
= T
