AMC1100DWVR Description

AMC1100DWVR is a type of low-cost basic isolated amplifier with precision current sensing. Its output is separated from the input circuitry by a silicon dioxide (SiO2) barrier highly resistant to magnetic interference. Noise currents on a high common-mode voltage line are prevented from entering the local ground and interfering with or damaging sensitive circuitry when this device is used with isolated power supplies. It operates with a temperature range from –40°C to +105°C. AMC1100DWVR isolated amplifier is available in the SMD-type, wide-body SOIC-8 (DWV) and gullwing-8 (DUB) packages for the purpose of saving PCB space.
