6559f

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 speciﬁed 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 ampliﬁers have their outputs short circuited.

Note 4: The LT6559 is guaranteed to meet speciﬁed 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 speciﬁcation 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 ampliﬁer 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 speciﬁcations which apply over the speciﬁed

operating temperature range, otherwise speciﬁcations are at TA = 25°C. For each ampliﬁer: VCM = 0V, VS = ±5V, ⎯E⎯N = 0V, pulse tested,

unless otherwise noted. (Note 4)
