LOGARITHMIC AMPLIFIER
DESCRIPTION
Packaged in a ceramic double wide DIP, the 4127 is
the first hybrid logarithmic amplifier that accepts
signals of either polarity from current or voltage
sources. A special purpose monolithic chip, devel-
oped specifically for logarithmic conversions,
functions accurately for up to six decades of input
current and four decades of input voltage. In addition,
a current inverter and a precise internal reference
allow pin programming of the 4127 as a logarithmic,
log ratio, or antilog amplifier.
To further increase its versatility and reduce your
system cost, the 4127 has an uncommitted operational
amplifier in its package that can be used as a buffer,
inverter, filter, or gain element.
The 4127 is available with initial accuracies (log
conformity) of 0.5% and 1.0%, and operates over an
ambient temperature range of –10
°C to +70°C.
With its versatility and high performance, the 4127
has many applications in signal compression, trans-
ducer linearization, and phototube buffering.
Manufacturers of medical equipment, analytical
instruments, and process control instrumentation will
find the 4127 a low cost solution to many signal
processing problems.
