The AMC1204-Q1 is a 1-bit digital output, isolated delta-sigma (ΔΣ) modulators that can be clocked at up to 20 MHz. 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 4250 VPEAK according to UL1577, IEC60747-5-2, and CSA standards or specifications.
The AMC1204-Q1 provides a single-chip solution for measuring the small signal of a shunt resistor across an isolated barrier. These types of resistors are typically used to sense currents in motor control inverters, green energy generation systems, and other industrial applications. The AMC1204-Q1 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 78 kSPS.
A 5-V analog supply (AVDD) is used by the modulator while the isolated digital interface operates from a 3-V, 3.3-V, or 5-V supply (DVDD). The AMC1204-Q1 is available in SO-16 (DW) packages and are specified from –40°C to 125°C.
