3 Description

The AMC1100 is a precision isolation amplifier with

an output separated from the input circuitry by a

silicon dioxide (SiO2) barrier that is highly resistant to

magnetic interference. This barrier is certified to

provide galvanic isolation of up to 4250 VPEAK,

according to DIN VDE V 0884-11: 2017-01 and

UL1577. Used in conjunction with isolated power

supplies, this device prevents noise currents on a

high common-mode voltage line from entering the

local ground and interfering with or damaging

sensitive circuitry.

The AMC1100 input is optimized for direct connection

to shunt resistors or other low voltage level signal

sources. The excellent performance of the device

enables accurate current and voltage measurement

in energy-metering applications. The output signal

common-mode voltage is automatically adjusted to

either the 3-V or 5-V low-side supply.

The AMC1100 is fully specified over the extended

industrial temperature range of –40°C to +105°C and

is available in the SMD-type, wide-body SOIC-8

DWV) and gullwing-8 (DUB) packages.
