AMC1304x Precision Delta-Sigma (ΔΣ) Modulators

Texas Instruments AMC1304x Precision Delta-Sigma (ΔΣ) Modulators include the output separated from the input circuitry by a capacitive double isolation barrier. This makes these devices highly resistant to magnetic interference. This barrier is certified to provide reinforced isolation of up to 7000V_PEAK according to the DIN V VDE V 0884-10, UL1577 and CSA standards. Used in conjunction with isolated power supplies, these devices prevent noise currents on a high common-mode voltage line from entering the local system ground. They also prevent interfering with or damaging low voltage circuitry. The input of the AMC1304x is optimized for direct connection to shunt resistors or other low voltage-level signal sources. The unique low input voltage range of the ±50mV device allows a significant reduction of the power dissipation through the shunt. This helps to support excellent AC and DC performance.
