LH4002A / LH4002 / LH4002C

FEATURES

  • • DC to 300 MHz Bandwidth with VS = ±5V
  • • 3000 V/µs Slew Rate into 50Ω

APPLICATIONS

  • • Wideband Amplifier Buffer
  • • Wideband Line Driver
  • • Video
  • • Coaxial Cable Driver GENERAL DESCRIPTION The LH4002 family is a high speed voltage follower designed to drive video signals from DC up to 300MHz. At voltage supplies of ±5V, the LH4002 family will provide up to 80mA into 50Ω at slew rates of 2000 V/µs. The LH4002 family is intended to fulfill a wide range of high speed applications including video distribution, impedance transformation, and load isolation. It is also suitable for use in current booster applications within an op amp loop. This allows the output current capability of existing op amps to be increased.

DC and AC electrical specifications do not apply when operating the device beyond its rated operating conditions. Note 2: Slew rate is measured with 50Ω source impedance at 25oC. For accurate measurements, the input slew rate should be at least 5000V/µs. Note 3: The test circuit consists of the human body model of 120pF in series with 1500Ω . Note 4: The maximum power dissipation is a function of TJ(max), θJA and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max) - TA)/θJA. Note 5: Limits are guaranteed by testing, correlation or periodic characterization. Note 6: For N package, θJA is measured by soldering the unit directly on a printed circuit board and V- pins are connected to 2 square inches of 2 oz copper.
