DESCRIPTION
The ISO100 is an optically-coupled isolation ampli-
fier. High accuracy, linearity, and time-temperature
stability are achieved by coupling light from an LED
back to the input (negative feedback) as well as for-
ward to the output. Optical components are carefully
matched and the amplifier is actively laser-trimmed to
assure excellent tracking and low offset errors.
The circuit acts as a current-to-voltage converter with
a minimum of 750V (2500V test) between input and
output terminals. It also effectively breaks the gal-
vanic connection between input and output commons
as indicated by the ultra-low 60Hz leakage current of
0.3µA at 250V. Voltage input operation is easily
achieved by using one external resistor.
Versatility along with outstanding DC and AC perfor-
mance provide excellent solutions to a variety of
challenging isolation problems. For example, the
ISO100 is capable of operating in many modes, in-
cluding: noninverting (unipolar and bipolar) and in-
verting (unipolar and bipolar) configurations. Two
precision current sources are provided to accomplish
bipolar operation. Since these are not required for
unipolar operation, they are available for external use
(see Applications section).
Designs using the ISO100 are easily accomplished
with relatively few external components. Since VOUT
of the ISO100 is simply IINRF, gains can be changed
by altering one resistor value. In addition, the ISO100
has sufficient bandwidth (DC to 60kHz) to amplify
most industrial and test equipment signals.
