    Digital to Analog Converter, also referred to as D/A. This is the circuitry that translates a binary data word to a specific voltage level. The two DACs on the DaqBoard/500 are specified for DC accuracy. The DACs can be clocked and triggered. The DAC outputs are updated as soon as they receive new data.
  • Page 32 These include ADC resolution (16-bits), gain setting, and sampling mode. DaqBoard/500 Series boards use16-bit ADC chips. The chips sample at rates up to 200 kilo-samples per second. These limits may not be exceeded. If the sample clock runs faster some of the clock pulses will be ignored by the circuitry, and a clock error will be generated.
