AMC1304L05DW Datasheet PDF - TI

●The AMC1304L05DW is a precision delta-sigma™ (ΔΣ) Modulator with 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 7000VPEAK. Used in conjunction with isolated power supplies, the device prevents noise currents on a high common-mode voltage line from entering the local system ground and interfering with or damaging low voltage circuitry. The input of the AMC1304 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 significant reduction of the power dissipation through the shunt while supporting excellent AC and DC performance. By using an appropriate digital filter to decimate the bit stream, the device can achieve 16-bit of resolution with a dynamic range of 81dB at a data rate of 78kSPS.
