The AMC3306M05 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 VDE V 0884-11 and UL1577 and supports a working voltage of up to 1.2 kVRMS.
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 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 measurments over the extended industial temperature range from –40°C to +125°C.
By using a digital filter (such as a sinc3 filter) to decimate the bitstream, the device can achieve 16 bits of resolution with a dynamic range of 85 dB at a data rate of 78 kSPS.
