Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 4: Ramp Pin 8 voltage down from 15V while measuring IS. When IS
drops to less than 0.5mA, measure Pin 8 current.
Note 2: A heat sink may be required depending on the power supply
voltage.
Note 3: The supply current of the LT1227 has a negative temperature
coefficient. For more information, see Typical Performance Characteristics
curves.
Note 5: Slew rate is measured at ±5V on a ±10V output signal while
operating on ±15V supplies with RF = 2k, RG = 220Ω and RL = 400Ω.
Note 6: AC parameters are 100% tested on the ceramic and plastic DIP
package 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.
