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. The
LH0033 slews at 1500V/
μ
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
coaxial
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. The LH0033 is specified for
operation from -55
o
C to +125
o
C and the LH0033C is specified
from -25
o
C to 85
o
C. The LH0033 is available in a 2.2W metal
TO-8 package.
