The AMC1303 (AMC1303x0510, AMC1303x0520, AMC1303x2510, and AMC1303x2520) is a family of precision, isolated delta-sigma (ΔΣ) modulators. The output is separated from the input circuitry by a capacitive isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced isolation of up to 7000VPK according to the DIN EN IEC 60747-17 (VDE 0884-17) and UL1577 standards, and supports a working voltage up to 1.5kVRMS
The input of the AMC1303 device is optimized for direct connection to shunt resistors or other, low-impedance signal sources. The small size, high DC accuracy, low temperature drift, and high common-mode transient immunity (CMTI) support accurate isolated current sensing in noisy high-voltage applications.
The output bitstream of the AMC1303 is synchronized to the internally generated clock and is Manchester coded (AMC1303Ex) or uncoded (AMC1303Mx). Combined with a digital low-pass filter (such as a Sinc-filter) the device achieves 85dB of dynamic range at an effective output data rate of 78kSPS.
