REFERENCE INPUT CHARACTERISTICS
(1) Test limits are guaranteed to TI's AOQL (Average Outgoing Quality Level).
(2) This parameter is guaranteed by design and/or characterization and is not tested in production.
(3) This parameter does not represent a condition which the DAC can sustain continuously. See the continuous output current specification
for the maximum DAC output current per channel.
