The AMC1304 family from Texas Instruments offers precision, delta-sigma (ΔΣ) modulators with the output separated from the input circuitry by a capacitive isolation barrier that is highly resistant to magnetic interference.
This barrier is certified to provide reinforced isolation of up to 7000 VPEAK according to the UL1577 and VDE V-0884-10 standards. Used in conjunction with isolated power supplies, the device prevents noise currents on a high common-mode voltage line from entering the local ground and interfering with or damaging sensitive circuitry. The input of the AMC1304 is optimized for direct connection to shunt resistors or other low-voltage level signal sources.
The low input voltage range of the device allows significant reduction of the power dissipation through the shunt while supporting excellent ac and dc performance. On the high-side, the modulator is supplied with an integrated LDO regulator that allows an unregulated voltage to be applied between 4 V and 18 V. The isolated digital interface operates from a 3.0-V to 5.5-V supply (DVDD). The AMC1304 is available in a wide-body SOIC-16 (DW) package.
