This barrier is certified to provide reinforced isolation of up to 7000 VPEAK according to the DIN V VDE V 0884-11 and UL1577 standards. Used in conjunction with isolated power supplies, this isolated modulator separates parts of the system that operate on different mon-mode voltage levels and protects lower-voltage parts from damage. The input of the AMC1306 is optimized for direct connection to shunt resistors or other low voltagelevel signal sources. The unique low input voltage range of the ±50-m V device allows significant reduction of the power dissipation through the shunt and supports excellent ac and dc performance. The output bitstream of the AMC1306 is Manchester coded (AMC1306Ex) or uncoded (AMC1306Mx), depending on the derivate. By using an integrated digital filter (such as those in the TMS320F2807x or TMS320F2837x microcontroller...
