Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
A heat sink may be required to keep the junction temperature
below the Absolute Maximum Rating.
Note 3:
The LT6557C is guaranteed functional over the temperature range
of –40°C and 85°C.
Note 4:
The LT6557C is guaranteed to meet specified performance from
0°C to 70°C. The LT6557C is designed, characterized and expected to
meet specified performance from –40°C to 85°C but is not tested or
QA sampled at these temperatures.The LT6557I is guaranteed to meet
specified performance from –40°C to 85°C.
Note 5:
Slew rate is 100% production tested on the R channel and
measured on the rising edge of the output signal. The slew rate of the
falling edge and of the G and B channels is guaranteed through design and
characterization.
Note 6:
Large-signal bandwidth is calculated from slew rate:
