The LH0033 and LH0063 are high speed, FET input, voltage follower/buffers designed to provide high current drive at frequencies from DC to over 100 MHz.
LH0033***±10 mA into 1KR (±100 mA peak) @ 1500V/us.
LH0063***±250 mA into 50R (±500 mA peak) @ 6000V/us.
In addition, both exhibit excellent phase linearity up to 20 MHz.
Both are intended to fulfill a wide range of buffer applications such as high speed line drivers, video impedance transformation, nuclear instrumentation amplifiers, op amp isolation buffers for driving reactive loads and high impedance input buffers for high speed A to Ds and comparators.
In addition, the LH0063 can continuously drive 50R coaxial cables or be used as a yoke driver for high resolution CRT displays.
These devices are constructed using specially selected junction FETs and active laser trimming to achieve guaranteed performance specifications.
The LH0033 is available in either a 1.5W metal TO-8 package or an 8-pin ceramic dual-in-line package, LH0063 is available in a 5W 8-pin TO-3 package.
