NOTES:
2. Voltages at analog inputs and outputs, REF, VCC+, and VCC– are with respect to ANLG GND. Voltages at
digital inputs and outputs and VDD are with respect to DGTL GND.
3. The algebraic convention, in which the least positive (most negative) value is designated minimum, is used
in this data manual for logic voltage levels only.
4. The band-pass switched-capacitor filter (SCF) specifications apply only when the low-pass section SCF
clock is 288 kHz and the high-pass section SCF clock is 16 kHz. If the low-pass SCF clock is shifted from
288 kHz, the low-pass roll-off frequency shifts by the ratio of the low-pass SCF clock to 288 kHz. If the
high-pass SCF clock is shifted from 16 kHz, the high-pass roll-off frequency shifts by the ratio of the
high-pass SCF clock to 16 kHz. Similarly, the low-pass switched-capacitor filter (SCF) specifications apply
only when the SCF clock is 288 kHz. If the SCF clock is shifted from 288 kHz, the low-pass roll-off frequency
shifts by the ratio of the SCF clock to 288 kHz.
5. This range applies when (IN+ – IN–) or (AUX IN+ – AUX IN–) equals
±
6 V.
