ATA6824 [Preliminary]

3. General Statement and Conventions

• Parameter values given without tolerances are indicative only and not to be tested in

production

• Parameters given with tolerances but without a parameter number in the first column of

parameter table are “guaranteed by design” (mainly covered by measurement of other

specified parameters). These parameters are not to be tested in production. The tolerances

are given if the knowledge of the parameter tolerances is important for the application

• The lowest power supply voltage is named GND

• All voltage specifications are referred to GND if not otherwise stated

• Sinking current means that the current is flowing into the pin (value is positive)

• Sourcing current means that the current is flowing out of the pin (value is negative)
