tr Small-Signal Rise Time VS = ±12V, AV = 2 3.5 ns Rise and Fall Time VS = ±5V, AV = 2, VOUT = 1VP-P 5.2 ns tp Propagation Delay VS = ±5V, AV = 2 3.5 ns
Note 1:
A heat sink may be required to keep the junction temperature LT1252CN8: TJ = TA + (PD × 100°C/W) below absolute maximum when the output is shorted indefinitely. LT1252CS8: TJ = TA + (PD × 150°C/W)
Note 2:
TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formulas:
