Figure 30. KLUT Example
The KLUT data is stored in straight binary format.
Figure 30 details a channel 1 KLUT example with nine
entries, a range of 0.5V to 1.7V, and a step size of 256.
Assuming V_REFDAC = +2.5V, the base value (819d) is
determined by the following equation:
0.5V _{x 4096 = 819d}
2.5V
Internally Timed Acquisitions
and Conversions
Clock Mode 00
In clock mode 00, power-up, acquisition, conversion,
and power-down are all initiated by writing to the ADC
conversion register and performed automatically using
the internal oscillator. This is the default clock mode.
With ADCMON set to 1, the ADC sets the BUSY output
high, powers up, scans all requested channels, stores
the results in the FIFO, and then powers down. After the
scan is complete, the BUSY output is pulled low and
the results are available in the FIFO.
