The AMC3306M05-Q1 is a precision, isolated delta-sigma (ΔΣ) modulator, optimized for shunt-based current measurements. The fully integrated, isolated DC/DC converter allows single-supply operation from the low-side of the device which makes the device a unique solution for space-constrained applications. The reinforced capacitive isolation barrier is certified according to DIN EN IEC 60747-17 (VDE 0884-17) and UL1577 and supports a working voltage up to 1.2kVRMS.

The isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects the low-voltage side from hazardous voltages and damage.

The input of the AMC3306M05-Q1 is optimized for direct connection to a low-impedance shunt resistor or other, low-impedance voltage source with low signal levels. The excellent DC accuracy and low temperature drift supports accurate current measurements over the extended industrial temperature range from –40°C to +125°C.

Use a digital filter (such as a sinc3 filter) to decimate the bitstream. By using this digital filter, the device achieves 16 bits of resolution with an 85dB dynamic range at a data rate of 78kSPS.
