10.D/A CONVERTER
74
Example of Setting
In the case where:
D/A output mode ................ 0 (linked with indicated value)
D/A zero setting .................. 00100
D/A full scale setting .......... 02100
10-1-3. About D/A Resolution
The resolution of the D/A converter is 1/6000 with respect to 0 to ±10V.
In other words, the minimum unit of voltage is:
(+10 to (-10V)) × 1/6000 = 3.33mV.
Also, the minimum unit of indicated value is:
(D/A full scale set value - D/A zero set value) × 2 × 1/6000.
