The q denotes specifications which apply over the operating temperature
range.
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 RF = 1k, RG = 110Ω and RL = 400Ω. The
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 RF = 1k, RG = 110Ω and RL =
100
Ω. 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 2VP.
Each Amplifier, VCM = 0V, ±5V ≤ VS = ±15V, pulse tested unless otherwise noted.
