| Wideband Video Buffer CORPORATION LH4002A / LH4002 / LH4002C FEATURES GENERAL DESCRIPTION 5V 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 50 at slew rates of 2000 V/s. 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 50 source impedance at 25oC. For accurate measurements, the input slew rate should be at least 5000V/s. Note 3: The test circuit consists of the human body model of 120pF in series with 1500. Note 4: The maximum power dissipation is a function of T J(max), JA and TA. The maximum allowable power dissipation at any ambient temperature is PD = (T J(max) - TA)/JA. Note 5: Limits are guaranteed by testing, correlation or periodic characterization. Note 6: For N package, JA 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.
