Min/Max characteristics and specifications are guaranteed over all Operating Conditions.
Typical characteristics and specifications are measured at nominal supply voltages and TA = 25 °C.
VA+ = VD+ = 3 V ±10%; VA- = -2 V ±10%; AGND = DGND = 0 V. All voltages with respect to 0 V.
Logic Levels: Logic 0 = 0 V, Logic 1 = VD+
6. Specified using 10% and 90% points on wave-form of interest. Output loaded with 50 pF.
7. Device parameters are specified with XIN = 4.096 MHz.
8. Device parameters are specified with OWRS = 1.
9. After SE is asserted, the states of SDO and SCLK are FSO is undefined.
