Abstract:
Various apparatuses, methods and systems for a multi-mode DAC with selectable output range, granularity and offset and controlled slew rate are disclosed herein. For example, some embodiments of the present invention provide an apparatus for supplying a reference signal, including a digital-to-analog converter, a counter and a clock. The digital-to-analog converter has a digital input and an analog output that supplies a reference signal based on the digital input. The counter has a digital control word input, a clock input, a clock enable output and a count output connected to the digital input of the digital-to-analog converter. The counter is adapted to assert the clock enable output when the digital control word input requests an output count that is different from an actual count at the count output of the counter. The clock has an enable input connected to the clock enable output of the counter and a clock output connected to the clock input of the counter. The clock is adapted to produce clock pulses on the clock output while the enable input is asserted.
