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: This parameter is guaranteed to meet specied performance
through design and characterization. It has not been tested.
Note 3: A heat sink may be required depending on the power supply
voltage and how many ampliers have their outputs short circuited.
Note 4: The LT6559 is guaranteed to meet specied performance from 0°C
to 70°C and is designed, characterized and expected to meet these extended
temperature limits, but is not tested or QA sampled at –40°C and 85°C.
Note 5: TJ is calculated from the ambient temperature TA and the power
dissipation PD according to the following formula: TJ = TA + (PD 68°C/W)
Note 6: At ±5V, slew rate is measured at ±2V on a ±3V output signal. At 5V,
slew rate is measured from 2V to 3V on a 1.5V to 3.5V output signal. Slew
rate is 100% production tested at ±5V for both the rising and falling edge
of the B channel. The slew rate of the R and G channels is guaranteed
through design and characterization.
Note 7: Turn-on delay time (tON) is measured from control input to
appearance of 1V at the output, for VIN = 1V. Likewise, turn-off delay
time (tOFF) is measured from control input to appearance of 0.5V on the
output for VIN = 0.5V. This specication is guaranteed by design and
characterization.
Note 8: Differential gain and phase are measured using a Tektronix
TSG120YC/NTSC signal generator and a Tektronix 1780R Video
Measurement Set. The resolution of this equipment is 0.1% and 0.1°. Ten
identical amplier stages were cascaded giving an effective resolution of
0.01% and 0.01°.
Note 9: The LT6559 is guaranteed functional over the operating
temperature range of –40°C to 85°C.

The ● denotes specications which apply over the specied
operating temperature range, otherwise specications are at TA = 25°C. For each amplier: VCM = 0V, VS = ±5V, EN = 0V, pulse tested,
unless otherwise noted. (Note 4)
