ISD4002 SERIES
Notes:
[1] Typical values @ TA = 25°C, VCC = 3.0V and timing measurement at 50%.
[2] All Min/Max limits are guaranteed by Winbond via electrical testing or characterization. Not all
specifications are 100 percent tested.
[3] Low-frequency cutoff depends upon the value of external capacitors (see Pin Descriptions)
[4] Single-ended input mode. In the differential input mode, VIN maximum for ANA IN+ and ANA IN- is 16
mVp-p.
[5] 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)
[6] 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)
[7] 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.
[8] The typical output voltage will be approximately 450 mVp-p with VIN at 32 mVp-p.
[9] For optimal signal quality, this maximum limit is recommended.
[10] When a record command is sent, TRAC = TRAC + TRACL on the first row address.
