Note 2:
Absolute maximum ratings are limiting values, to be applied individually, and beyond which the serviceability of the circuit may be impaired. Functional
operability under any of these conditions is not implied. Exposure to maximum ratings for extended periods may affect device reliability.
Note 3:
Data sheet min/max specification limits are guaranteed by design or statistical analysis.

Applications Information
POWER-UP TIMING
The SCANSTA476 typically requires 1 μs to power up ,
either after first applying V
, or after an incomplete conver-
sion shift. To return to normal, one "dummy" conversion must
be fully completed. After this first dummy conversion, the
SCANSTA476 will perform conversions properly.
STARTUP MODE
When the V
supply is first applied, the SCANSTA476
requires one dummy conversion after start-up.
