Note 1: A heat sink may be required depending on the power supply
voltage and how many amplifiers are shorted.
Note 2: The power tests done on 15V supplies are done on only one
amplifier at a time to prevent excessive junction temperatures when testing
at maximum operating temperature.
Note 3: The supply current of the LT1229/LT1230 has a negative
temperature coefficient. For more information see the application
information section.
Note 4: Slew rate is measured at 5V on a 10V output signal while
operating on 15V supplies with R

slew rate is much higher when the input is overdriven and when the
amplifier is operated inverting, see the applications section.
Note 5: Rise time is measured from 10% to 90% on a 500mV output
signal while operating on 15V supplies with R
100 . This condition is not the fastest possible, however, it does
guarantee the internal capacitances are correct and it makes automatic
testing practical.
Note 6: AC parameters are 100% tested on the ceramic and plastic DIP
packaged parts (J and N suffix) and are sample tested on every lot of the
SO packaged parts (S suffix).
Note 7: NTSC composite video with an output level of 2V
