The q denotes specifications which apply over the full operating

temperature range.

Note 1: Applies to short circuits to ground only. A short circuit between the

output and either supply may damage the part when operated on supplies

greater than

±10V

Note 2: The LT1497 is designed, characterized and expected to operate

over the temperature range of – 40

°C to 85°C, but is not tested at –40°C

and 85

°C. Guaranteed industrial grade parts are available, consult factory.

Note 3: Thermal resistance varies depending upon the amount of PC board

metal attached to the device.

θJA is specified for a 2500mm2 test board

covered with 2oz copper on both sides.

Note 4: Slew rate is measured between

±5V on a ±10V output signal while

operating on

±15V supplies with RF = 453Ω, RG = 49.9Ω and RL = 150Ω.

±5V supplies slew rate is measured between ±1V on a ±3V output

signal. The slew rate is much higher when the input is overdriven and

when the amplifier is operated inverting. See the Applications Information

section.

Note 5: NTSC composite video with an amplifier output level of 2V peak.
