The digital isolation of the • Certified Digital Isolation: modulator output is provided by a silicon dioxide – CSA, IEC60747-5-2, and UL1577 Approved (SiO2) barrier that is highly resistant to magnetic interference. This barrier has been certified to provide – Isolation Voltage: 4250VPEAK (AMC1204B) basic galvanic isolation of up to 4000VPEAK – Working Voltage: 1200VPEAK (AMC1204) and 4250VPEAK (AMC1204B) according to – Transient Immunity: 15kV/µs UL1577, IEC60747-5-2, and CSA standards or specifications. • Long Isolation Barrier Lifetime (see Application Report SLLA197) The AMC1204 and AMC1204B provide a single-chip solution for measuring the small signal of a shunt • High Electromagnetic Field Immunity resistor across an isolated barrier. These types of (see Application Note SLLA181A) resistors are typically used to sense currents in motor • Outstanding AC Performance: control inverters, green energy generation systems, – SNR: 84dB (min) and other industrial applications. The AMC1204 and AMC1204B differential inputs easily connect to the – THD: –80dB (max) shunt resistor or other low-level signal sources. An • Excellent DC Precision: internal reference eliminates the need for external – INL: ±8LSB (max) components. When used with an appropriate external – Gain Error: ±2% (max) digital filter, an effective number of bits (ENOB) of 14 is achieved at a data rate of 78kSPS. • External Clock Input for Easier Synchronization A 5V analog supply (AVDD) is used by the modulator while the isolated digital interface operates from a 3V, • Fully Specified Over the Extended Industrial 3.3V, or 5V supply (DVDD). The AMC1204 and Temperature Range AMC1204B are available in SO-16 (DW) packages and are specified from –40°C to +105°C. APPLICATIONS • Shunt Resistor Based Current Sensing in: – Motor Control – Green Energy – Inverter Applications – Uninterruptible Power Supplies 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
