3 Description

The AMC1200 and AMC1200B are precision isolation
amplifiers with an output separated from the input
circuitry by a silicon dioxide sio)barrier that is
highly resistant to magnetic interference.This barrier
has been certified to provide gaivanic isolation ofup
to 4250 VPEAK(AMC1200B)or 4000 VPEAK
(AMC1200 according to UL1577 and VDE V0884-
10. Used in conjunction with isolated power supplies
these devices prevent noise currents on ahigh
common mode voltage line from entering the local
ground and interfering with ordamagingsensitive
circuitry.
The input of the AMC1200 or AMC1200B is optimized
for direct connection to shunt resistors orother low
voltage level signalsources.The
excellent
performance of the device supports accurate current
control resulting in system-level power savingand
especially in motor-control applicationslower torque
ripple. The common mode voltage of the output
signal is automatically adjusted to either the3-Vor
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 awide body
SOlC-8 package (DWand a gullwing-8 package
(DUB).
