General Description
The ELH0033 is a high-speed FET input voltage follower buff-
er designed to provide high output currents from DC to over
100 MHz The ELH0033 slews at 1500 V
ms and will drive 100X
loads Phase linearity is excellent to 20 MHz allowing the buff-
er to be included in op amp loops
The ELH0033 is intended to fulfill a wide range of buffer appli-
cations such as high-speed line drivers video impedance trans-
formation nuclear instrumentation amplifiers op amp isolation
buffers for driving reactive loads and high impedance input
buffers for high-speed A to D's and comparators
These devices are constructed using specially selected junction
FETs and active laser trimming to achieve guaranteed perform-
ance specifications The ELH0033 is specified for operation
