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 boost er appl ications within an op amp loop. This allows
the output current capability of existing op amps to be increased.
