The ● 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. θ
JA
is specified for a 2500mm
2
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 R
F
= 453Ω, R
G
= 49.9Ω and R
L
= 150Ω.
On ±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.
