DESCRIPTION
The ISO130 is a high isolation-mode rejection, isola-
tion amplifier suited for motor control applications. Its
versatile design provides the precision and stability
needed to accurately monitor motor currents in high-
noise motor control environments. The ISO130 can
also be used for general analog signal isolation appli-
cations requiring stability and linearity under severe
noise conditions.
The signal is transmitted digitally across the isolation
barrier optically, using a high-speed AlGaAs LED.
The remainder of the ISO130 is fabricated on 1
m
CMOS IC process. A sigma-delta analog-to-digital
converter, chopper stabilized amplifiers and differen-
tial input and output topologies make the isolation
amplifier suitable for a variety of applications.
The ISO130 is easy to use. No external components
are required for operation. The key specifications are
10kV/
s isolation-mode rejection, 85kHz large signal
bandwidth, and 4.6
V/
C V
OS
drift. A single power
supply ranging from +4.5V to +5.5V makes this am-
plifier ideal for low power isolation applications.
The ISO130 is available in 8-pin plastic DIP and 8-pin
plastic gull-wing surface mount packages.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
