ISD
1. Typical values: T
A
= 25°C and 3.0 V.
2. All min/max limits are guaranteed by ISD via electrical testing or characterization. Not all specifications are 100
percent tested.
3. Low-frequency cut off depends upon the value of external capacitors (see Pin Descriptions).
4. Single-ended input mode. In the differential input mode, V
IN
maximum for ANA IN+ and ANA IN– is 16 mV peak-
to-peak.
5. Sampling Frequency and Duration can vary as much as ±2.25 percent over the commercial temperature and
voltage ranges. For greater stability, an external clock can be utilized (see Pin Descriptions).
6. Filter specification applies to the antialiasing filter and to the smoothing filter.
7. The typical output voltage will be approximately 570 mV peak-to-peak with V
IN
at 32 mV peak-to-peak.
8. For optimal signal quality, this maximum limit is recommended.
9. When a record command is sent, T
RAC
= T
RAC
+ T
RACLO
on the first row addressed.
1. Typical values: T
A
= 25°C and 3.0 V. Timing measured at 50 percent of the V
CC
level.
2. Tristate test condition.
