74 The analog output voltage on each DAC channel pin is determined
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
75 by the following equation:
5f11787b4f42 include in ostc4 repository

parents:

76 DAC_OUTx = VREF+ * DOR / 4095
5f11787b4f42 include in ostc4 repository

77 with DOR is the Data Output Register

78 VEF+ is the input voltage reference (refer to the device datasheet)

79 e.g. To set DAC_OUT1 to 0.7V, use
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:

80 Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
