The AMC1305M05DW 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 AMC1305 is optimized for direct connection to shunt resistors or other low voltage level signal sources while supporting excellent DC and AC performance. Shunt resistors are typically used to sense currents in motor drives, green energy generation systems or other industrial applications. By using an appropriate digital filter to decimate the bit stream, the device can achieve 16 bits of resolution with a dynamic range of 85dB at a data rate of 78kSPS.
