Typical values @ T
All Min/Max limits are guaranteed by Winbond via electrical testing or characterization. Not all
specifications are 100 percent tested.
Low-frequency cutoff depends upon the value of external capacitors (see Pin Descriptions)
Single-ended input mode. In the differential input mode, V
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 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 industrial temperature and voltage ranges. 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 6 dB drop by nature of passing through both filters.
The typical output voltage will be approximately 450 mVp-p with V
For optimal signal quality, this maximum limit is recommended.
When a record command is sent, T
