Note 1: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 2: TJ is calculated from the ambient temperature TA and power
dissipation PD according to the following formulas:
LT1252CN8: TJ = TA + (PD × 100°C/W)
LT1252CS8: TJ = TA + (PD × 150°C/W)

Note 1: Differential Gain and Phase are measured using a Tektronix TSG
120 YC/NTSC signal generator and a Tektronix 1780R Video Measurement
Set. The resolution of this equipment is 0.1% and 0.1°. Ten identical
