7.4.2 Power-Up Timing
The ADCS747x typically requires 1 µs to power up, either after first applying V
DD
, or after returning to normal
mode from shutdown mode. This corresponds to one dummy conversion for any SCLK frequency within the
specifications in this document. After this first dummy conversion, the ADCS747x performs conversions properly.
NOTE
The t
QUIET
time must still be included between the first dummy conversion and the second
valid conversion.
