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.

Note 2: The supply current of the LT1227 has a negative temperature

coefficient. For more information, see Typical Performance Characteristics

curves.

Note 3: Ramp pin 8 voltage down from 15V while measuring IS. When IS

drops to less than 0.5mA, measure pin 8 current.

Note 4: 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 5: 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 6: NTSC composite video with an output level of 2V.
