3 Description
The AMC1200 and AMC1200B are precision isolation amplifiers
with an output separated from the input circuitry
by a silicon dioxide (SiO2) barrier that ishighly resistant to
magnetic interference.
This barrier has been certified to provide galvanic isolation of up
to 4250 VpEAK (AMC1200B)
or 4000 VpEAK (AMC1200) according to UL1577 and VDE V 0884-10.
Used in conjunction with isolated power supplies,
these devices prevent noise currents on a high
common mode voltage line from entering the local ground
and interfering with or damaging sensitive circuitry.
The input of the AMC1200 or AMC1200B is optimized
for direct connection to shunt resistors or other low voltage level
signal sources.
The excellent performance of the device supports accurate current
control resulting in system-level power saving and,
especially in motor-control applications, lower torque ripple.
The common mode voltage of the output signal is automatically
adjusted to either the 3-V or 5-V low-side supply.
The AMC1200 and AMC1200B are fully specified over
the extended industrial temperature range of. - -40°C to 105°C
and are available in a wide-body SOIC-8 package (DWV) and a
gullwing-8 package (DUB).
