TI AMC1411-Q1 Isolated Amplifier

TI AMC1411-Q1 Isolated Amplifier
Texas Instruments AMC1411-Q1 High Impedance Reinforced Isolated Amplifier is isolated between the output and input circuits by a capacitive isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced galvanic isolation up to 7.5kVRMS in compliance with VDE-V 0884-10 and UL1577 standards. Texas Instruments AMC1411-Q1 supports operating voltages up to 1600VRMS. This isolation barrier isolates parts of the system that operate at different common-mode voltage levels and protects the low-voltage side from voltages that could cause electrical damage or operator injury.
The high-impedance input of the Texas Instruments AMC1411-Q1 is optimized for interfacing with high-impedance resistive dividers or other high-impedance voltage signal sources. Excellent DC accuracy and low temperature drift support accurate, isolated voltage detection for on-board chargers (OBCs), DC/DC converters, traction inverters, or other applications that must operate at high common-mode voltages, high altitudes, or environmental pollution high-level applications.
