Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 6:
VIN LIM is the maximum voltage between –VIN and +VIN (Pin 2 and may cause permanent damage to the device. Exposure to any Absolute Pin 3) for which the output can respond. Maximum Rating condition for extended periods may affect device
Note 7:
Slew rate is measured between ±0.5V on the output, with a VIN reliability and lifetime. step of ±0.75V, AV = 3 and RL = 1k.
Note 2:
A heat sink may be required to keep the junction temperature
Note 8:
Full power bandwidth is calculated from the slew rate below absolute maximum when the output is shorted continuously. measurement: FPBW = SR/2πVP.
Note 3:
TJ is calculated from the ambient temperature TA and power
Note 9:
Settling time measurement techniques are shown in “Take the dissipation PD according to the following formulas: Guesswork Out of Settling Time Measurements,” EDN, September 19, LT1187MJ8, LT1187CJ8: TJ = TA + (PD • 100°C/W) 1985. LT1187CN8: TJ = TA + (PD • 100°C/W)
Note 10:
NTSC (3.58MHz). LT1187CS8: TJ = TA + (PD • 150°C/W)
Note 11:
AC parameters are 100% tested on the ceramic and plastic DIP
Note 4:
When RL = 1k is specified, the load resistor is RFB1 + RFB2, but packaged parts (J8 and N8 suffix) and are sample tested on every lot of when RL = 300Ω is specified, then an additional 430Ω is added to the the SO packaged parts (S8 suffix). output such that (RFB1 + RFB2) in parallel with 430Ω is RL = 300Ω.
Note 12:
See Application section for shutdown at elevated temperatures.
