±1-V input, precision voltage sensing reinforced isolated amplifier with integrated DC/DC

The AMC3330 is a precision, isolated amplifier with a fully integrated, isolated DC/DC converter that allows single-supply operation from the low-side of the device. The reinforced capacitive isolation barrier is certified according to DIN EN IEC 60747-17 (VDE 0884-17) and UL1577 and separates sections of the system that operate on different common-mode voltage levels and protects low-voltage domains from damage.

The input of the AMC3330 is optimized for direct connection to high-impedance, voltage-signal sources such as a resistor-divider network to sense high-voltage signals. The integrated isolated DC/DC converter allows measurement of non-ground-referenced signals and makes the device a unique solution for noisy, space-constrained applications.

The excellent performance of the device supports accurate voltage monitoring and control. The integrated DC/DC converter fault-detection and diagnostic output pin of the AMC3330 simplify system-level design and diagnostics.

The AMC3330 is specified over the temperature range of –40°C to +125°C.
