Description for the AMC1204

The AMC1204 and AMC1204B are 1-bit digital output, isolated delta-sigma (ΔΣ) modulatorsthat can be clocked at up to 20 MHz. The digital isolation of the modulator output is provided by asilicon dioxide (SiO2) barrier that is highly resistant to magneticinterference. This barrier has been certified to provide basic galvanic isolation of up to 4000VPEAK (AMC1204) and 4250 VPEAK (AMC1204B) accordingto UL1577, VDE V 0884-11, and CSA standards or specifications.

The AMC1204 and AMC1204B provide a single-chip solution for measuring the small signal ofa shunt resistor across an isolated barrier. These types of resistors are typically used to sensecurrents in motor control inverters, green energy generation systems, and other industrialapplications. The AMC1204 and AMC1204B differential inputs easily connect to the shunt resistor orother 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 isachieved at a data rate of 78 kSPS.

A 5-V analog supply (AVDD) is used by the modulator while the isolated digital interfaceoperates from a 3-V, 3.3-V, or 5-V supply (DVDD). The AMC1204 and AMC1204B are available in SOIC-16(DW) and SOIC-8 (DWV) packages and are specified from –40°C to 105°C.
