34. Digital to Analog Converter Controller (DACC)
34.1
34.2
11011A–ATARM–04-Oct-10
Description
Embedded Characteristics
The Digital-to-Analog Converter Controller (DACC) has one analog output, making it possible for
the digital-to-analog conversion to drive one analog line.
The DACC supports 10-bit resolution and data to be converted are sent in a common register.
External triggers, through the ext_trig pins, or internal triggers are configurable.
The DACC Controller connects with a PDC channel. This feature reduces processor
intervention.
Finally, the user can configure DACC timings such as Startup Time and the Internal Trigger
Period.
• 1 channel 10-bit DAC
• Up to 500 ksamples/s conversion rate
• Flexible conversion range
• Multiple trigger sources
• One PDC channel
