Appendix A Electrical Characteristics
A.7
This section describes the characteristics of the digital to analog converter.
A.7.1
A.8
A timing diagram of the external multiplexed-bus is illustrated in
values shown on table
While both a data write and data read cycle are shown, only one or the other would occur on a particular
bus cycle.
The expanded bus timings are highly dependent on the load conditions. The timing parameters shown
assume a balanced load across all outputs.
