Note 3: Thermal resistance
θJA varies from 40°C/W to 60°C/W 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: RSHDN is connected between the Shutdown pin and ground.
Note 5: Slew rate is measured at
±5V on a ±10V output signal while
operating on
±15V supplies with RF = 1.5k, RG = 1.5k and RL = 400.
Note 6: NTSC composite video with an output level of 2V.
The q denotes specifications which apply for 0
°C ≤ TA ≤ 70°C.
Note 1: Applies to short circuits to ground only. A short circuit between
the output and either supply may permanently damage the part when
operated on supplies greater than
±10V.
Note 2: Commercial grade parts are designed to operate over the
temperature range of – 40
°C to 85°C but are neither tested nor guaranteed
beyond 0
°C to 70°C. Industrial grade parts tested over –40°C to 85°C are
available on special request. Consult factory.
