Notes: 5. Common mode voltage may be at any value as long as AIN+ and AIN- remain within the VA+ and
VA- supply voltages.
6. XIN = 32.768 kHz. Guaranteed by design and / or characterization.
7. All outputs unloaded. Al l inputs CMOS levels. SLEEP mode controlled by M/SLP pin.
SLEEP active = M/SLP pin at (VD+)/2 input level.
