Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: May require a heat sink.
Note 3: The LT1675/LT1675-1 are guaranteed to meet specified
performance from 0 C to 70 C and are designed, characterized and
expected to meet these extended temperature limits, but are not tested at
– 40 C and 85 C. Guaranteed I grade parts are available; consult factory.

Note 5: Full power bandwidth is calculated from the slew rate
measurement:
Note 6: Differential Gain and Phase are measured using a Tektronix
TSG120 YC/NTSC signal generator and a Tektronix 1780R Video
Measurement Set. The resolution of this equipment is 0.1% and 0.1 . Nine
identical MUXs were cascaded giving an effective resolution of 0.011%
and 0.011 .
