DESCRIPTION
The ISO120 and ISO121 are precision isolation ampli-
fiers incorporating a novel duty cycle modulation-
demodulation technique. The signal is transmitted
digitally across a 2pF differential capacitive barrier.
With digital modulation the barrier characteristics do
not affect signal integrity, which results in excellent
reliability and good high frequency transient immu-
nity across the barrier. Both the amplifier and barrier
capacitors are housed in a hermetic DIP. The ISO120
and ISO121 differ only in package size and isolation
voltage rating.
These amplifiers are easy to use. No external compo-
nents are required for 60kHz bandwidth. With the
addition of two external capacitors, precision specifi-
cations of 0.01% max nonlinearity and 150
μ
V/
°
C max
V
drift are guaranteed with 6kHz bandwidth. A
power supply range of
±
4.5V to
±
18V and low quies-
cent current make these amplifiers ideal for a wide
range of applications.
