110 / 133 page  Electrical parameters STM8AL31E8x STM8AL3LE8x 110/133 DocID027180 Rev 5 In the following table, data are based on characterization results, not tested in production. Table 54. DAC accuracy Symbol Parameter Conditions Typ.

Not tested in production. 2. Difference between two consecutive codes - 1 LSB. 3. In 48-pin package devices the DAC2 output buffer must be kept off and no load must be applied on the DAC_OUT2 output. 4. Difference between measured value at Code i and the value at Code i on a line drawn between Code 0 and last Code 1023. 5. Difference between the value measured at Code (0x800) and the ideal value = VREF+/2. 6. Difference between the value measured at Code (0x001) and the ideal value. 7. Difference between the ideal slope of the transfer function and the measured slope computed from Code 0x000 and 0xFFF when buffer is ON, and from Code giving 0.2 V and (VDDA -0.2) V when buffer is OFF. |
