40. Digital-to-Analog Converter Controller (DACC)
40.1
40.2
6500C–ATARM–8-Feb-11
Description
Embedded Characteristics
The Digital-to-Analog Converter Controller (DACC) offers up to 2 analog outputs, making it possible for the
digital-to-analog conversion to drive up to 2 independent analog lines.
The DACC supports 12-bit resolution. Data to be converted are sent in a common register for all channels.
External triggers or free running mode are configurable.
The DACC integrates a Sleep Mode and connects with a PDC channel. These features reduce both power
consumption and processor intervention.
The user can configure DACC timings, such as Startup Time and Refresh Period.
• Up to 2 channels 12-bit DAC
• Up to 2 mega-samples conversion rate in single channel mode
• Flexible conversion range
• Multiple trigger sources for each channel
• 2 Sample/Hold (S/H) outputs
• Built-in offset and gain calibration
• Possibility to drive output to ground
• Possibility to use as input to analog comparator or ADC (as an internal wire and without S/H
• Two PDC channels
• Power reduction mode
stage)
