1 Chip Select Delay time (tCD) may be as short as 7 sec, if start of auto zero phase cycle time could be
determined. For asynchoronous operation, tCD must be for a minimum of one complete conversion cycle to
assure synchronization to start of auto zero phase cycle time.
2 These are typical practical limits for Integration time. Lower Integration time than the minimum allows more
conversion cycles per second at reduced count resolution.
Higher Integration time increases count
resolution, but requires increased capacitor value and lowered number of conversion cycles per second.
Deintegration time depends on selection of full scale input range, integration capacitor value and voltage
reference.
3 ESD Sensitive Device. Stresses above those listed under Absolute Maximum Ratings may cause permanent
damage to device and may affect device reliability.
