... J Note 9 Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level) Note 10 A monotonicity of 8 bits for the DAC0854 means that the output voltage changes in the same direction (or remains constant) for each increase in the input code Note 11 Integral linearity error is the maximum deviation of the output from the line drawn between zero and full-scale (excluding the effects of zero error and full- ...

... Digital Interface The DAC0854 has two interface modes a WRITE mode and a READ mode The WRITE mode is used to convert an 8-bit digital input word into a voltage The READ mode is used to read back the digital data that was sent to one or all of the DACs These modes are selected by the appropriate ...
