See the Typical Performance Characteristics.
See the Terminology section for a definition of the parameters.
See the Analog Inputs section.
Sample tested during initial release and after any redesign or process change that may affect this parameter. All input signals are specified with tr = tf = 5 ns (10% to
90%) and timed from a voltage level of 1.6 V.
See the timing diagrams in Figure 3 and Figure 4 and the Serial Interface section.
Minimum time between read command and data read for all registers except waveform register, which is t
Measured with the load circuit in Figure 2 and defined as the time required for the output to cross 0.8 V or 2.4 V.
Derived from the measured time taken by the data outputs to change 0.5 V when loaded with the circuit in Figure 2. The measured number is then extrapolated back
to remove the effects of charging or discharging the 50 pF capacitor. This means that the time quoted here is the true bus relinquish time of the part and is
independent of the bus loading.
