TEST LEVEL CODES
All electrical characteristics are subject to the
following conditions:
All parameters having min/max specifications
are guaranteed. The Test Level column indi-
cates the specific device testing actually per-
formed during production and Quality Assur-
ance inspection. Any blank section in the data
column indicates that the specification is not
tested at the specified condition.

DEFINITION OF SELECTED TERMINOLOGY
Channel-to-Channel Isolation
Channel-to-Channel isolation refers to the proportion of input signal from one DAC
’
s reference input that appears at the output of
the other DAC. It is expressed in dBs.
DAC-to-DAC Crosstalk
DAC-to-DAC crosstalk is defined as the glitch impulse that appears at one DAC
’
s output due to both the digital change and subse-
quent analog output change at any other DAC. It is specified in nV-s.
Digital Crosstalk
The glitch impulse transferred to one DAC
’
s output due to a change in digital input code of any other DAC. It is specified in nV-s.
Digital Feedthrough
Digital feedthrough is the noise at a DAC
’
s output caused by changes to D0
