DATA FORMAT
The output data from the ADS8321 is in Binary Two’s
Complement format as shown in Table II. This table repre-
sents the ideal output code for the given input voltage and
does not include the effects of offset, gain error, or noise.
POWER DISSIPATION
The architecture of the converter, the semiconductor fabrica-
tion process, and a careful design allow the ADS8321 to
convert at up to a 100kHz rate while requiring very little
power. Still, for the absolute lowest power dissipation, there
are several things to keep in mind.
The power dissipation of the ADS8321 scales directly with
conversion rate. Therefore, the first step to achieving the
lowest power dissipation is to find the lowest conversion rate
that will satisfy the requirements of the system.
In addition, the ADS8321 is in power-down mode under two
conditions: when the conversion is complete and whenever
CS is HIGH (see Figure 6). Ideally, each conversion should
occur as quickly as possible, preferably at a 2.4MHz clock
rate. This way, the converter spends the longest possible time
in the power-down mode. This is very important as the
converter not only uses power on each DCLOCK transition
(as is typical for digital CMOS components) but also uses
some current for the analog circuitry, such as the comparator.
The analog section dissipates power continuously, until the
power down mode is entered.
