The DACx1001 include a deglitch (track-and-hold) circuit at the output. This circuit is enabled by default. The deglitch circuit minimizes the code-to-code glitch at the DAC output at the expense of the DAC update rate. This circuit is disabled by writing 1 to DIS_TNH (bit 7, address 06h). Disable this circuit to enable faster update of the DAC output, but with higher code-to-code glitches.
