LH4001 Wideband Current Buffer
General Description
The LH4001 is a high speed unity gain buffer designed to
provide high current drive capability at frequencies from DC
to over 25 MHz It is capable of providing a continuous out-
put current of g100 mA and a peak of g200 mA
The LH4001 is designed to fulfill a wide range of applica-
tions such as impedance transformation high impedance
input buffers for A D converters and comparators as well
as high speed line drivers It is also suitable for use in cur-
rent booster applications within an op amp loop This allows
the output current capability of existing op amps to be in-
creased to g100 mA
