NOTES
1
In warp mode only, the maximum time between conversions is 1ms; otherwise, there is no required maximum time.
2
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.
3
In serial master read during convert mode. See Table I for serial master read after convert mode.
