The AMC1204DW is a 1-bit digital output isolated delta-sigma™ (ΔΣ) Modulator for current-shunt measurement. The digital isolation of the modulator output is provided by a silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference. This barrier has been certified to provide basic galvanic isolation of up to 4000VPEAK (AMC1204). It provides a single-chip solution for measuring the small signal of a shunt resistor across an isolated barrier. This type of resistor is typically used to sense currents in motor control inverters, green energy generation systems and other industrial applications. The AMC1204 differential inputs easily connect to the shunt resistor or other low-level signal sources. An internal reference eliminates the need for external components. When used with an appropriate external digital filter, an effective number of bits (ENOB) of 14 is achieved at a data rate of 78kSPS.
