Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are
the result of engineering evaluations. Typical values are for information purposes only and are not part of the test-
ing requirements. Stresses in excess of the absolute maximum ratings can cause permanent damage to the
device.
Table 4. LG1626DXC Minimum and Maximum Values
1. Maximum output modulation at maximum V
MOD
(R
L
= 50
).
2. Minimum output modulation when MOD_E is floating and V
MOD
= V
SS3.
3. Excludes I
PRE
and average I
MOD:
Power suppy current I
SS2
(relating to prebias) is dependent on V
PRE.
Power suppy current I
SS3
(relating to modulation) is dependent on V
MOD.
4. Both MK and MK are open drains, the typical value is obtained by driving a 1k
load.
5. Maximum modulator dc offset voltage (R
L
= 50
) at maximum V
DC-ADJ.
6. Minimum modulator dc offset voltage (R

= 50
) at V
DC-ADJ
= V
