TEXAS INSTRUMENTS AMC1204BDWVR 模数转换器, Δ-Σ, 16 bit, 78 kSPS, 单, 4.5 V, 5.5 V, SOIC
The AMC1204 and AMC1204B are 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 4000 VPEAK AMC1204 and 4250 VPEAK AMC1204B according to UL1577, VDE V 0884-10, and CSA standards or specifications.
The AMC1204 and AMC1204B provide 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 and AMC1204B 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 and AMC1204B are available in SOIC-16 DW and SOIC-8 DWV packages and are specified from –40°C to 105°C.
