NOTES
1
In serial interface modes, the SYNC, SCLK, and SDOUT timings are defined with a maximum load C
L
of 10 pF; otherwise, the load is 60 pF maximum.
2
In serial master read during convert mode. See Table I for serial master read after convert mode.
Specifications subject to change without notice.
(–40 C to +85 C, AVDD = DVDD
= 5 V, OVDD = 2.7 V to 5.25 V, unless otherwise noted.)
