GENERAL DESCRIPTION
The LH0033 is a high speed, FET input, voltage
follower/buffer designed to provide high current drive (up to
100mA) at frequencies from DC to over 100MHz.
LH0033 slews at 1500V/ s and exhibits excellent phase
linearity up to 20MHz.
LH0033 is 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 LH0033 can continuously drive 50
cables or be used as a yoke driver for high resolution CRT
displays.
This device is constructed using specially selected junction
FETs and active laser trimming to achieve guaranteed
performance specifications.

... APPLICATION INFORMATION: Recommended Layout Precautions RF/video printed circuit board layout rules should be followed when using the LH0033 since it will provide power gain to frequencies over 100MHz. Ground planes are recommended and power supplies should be decoupled at each device with low inductance capacitors. In addition, ground plane shielding may be extended to the metal case of the device since it is electrically isolated from internal circuitry ...

... LH0032, or CLM4124. An isolation resistor of 47 should be used between the op amp output and the input of LH0033. The wide bandwidth and high slew rate of the LH0033 assure that the loop has the characteristics of the op amp and that additional rolloff is not required. ...
