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 4: TJ is calculated from the ambient temperature TA and power
dissipation PD according to the following formula:
LT1675CGN: TJ = TA + (PD)(120°C/W)
LT1675CMS8-1: TJ = TA + (PD)(250°C/W)
LT1675CS8-1: TJ = TA + (PD)(150°C/W)
Note 5: Full power bandwidth is calculated from the slew rate
measurement:
FPBW = SR/2πVPEAK.
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°.
