Texas Instruments AMC1204 / AMC1204B
Delta-Sigma Modulators

Texas Instruments AMC1204 / AMC1204B second-order, isolated delta-sigma modulators can be clocked at up to 20MHz. TI AMC1204 / AMC1204B provides a single-chip solution for measuring the small signal of a shunt resistor across an isolated barrier. These TI delta-sigma modulators are used to sense currents in motor control inverters, green energy generation systems, and other industrial applications. The AMC1204 / AMC1204B differential inputs easily connect to the shunt resistor or other low-level signal sources.
