The ● denotes the speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations are at TA = 25°C. VS = 5V, RL = 150Ω to VS/2, VEN = 0.4V, RBCV = open, unless

otherwise noted.

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:

FPBW = SR/(π • VP-P)
