† _{Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and}
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: Voltage values for maximum ratings are with respect to VCC _–.

NOTES: 2. Voltages at analog inputs and outputs, REF, VCC _+, and VCC _–, are with respect to the ANLG GND terminal. Voltages at digital inputs
and outputs and VDD are with respect to the DGTL GND terminal.
3. The algebraic convention, in which the least positive (most negative) value is designated minimum, is used in this data sheet for
logic voltage levels and temperature only.
4. The bandpass 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 8 kHz. If the low-pass SCF clock is shifted from 288 kHz, the low-pass roll-off frequency will shift
by the ratio of the low-pass SCF clock to 288 kHz. If the high-pass SCF is shifted from 8 kHZ, the high-pass roll-off frequency will
shift by the ratio of the high-pass SCF clock to 8 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 will shift 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.
