AMC1303x High-Precision Delta-Sigma Modulators

Texas Instruments AMC1303x High-Precision Delta-Sigma Modulators have the output separated from the input circuitry by a capacitive double isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced isolation of up to 7000V_PK 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 common-mode voltage levels and protects lower-voltage parts from damage. The input of the AMC1303x is optimized for direct connection to shunt resistors or other low voltage-level signal sources. The ±50mV input voltage range option significantly reduces the power dissipation through the shunt. The output bit-stream of the AMC1303x is synchronized to the internally generated clock and is Manchester coded (AMC1303Ex) or uncoded (AMC1303Mx).
