AMC1303E2520 Reinforced Isolated Delta-Sigma Modulators

The AMC1303 (AMC1303x0510, AMC1303x0520, AMC1303x2510, and AMC1303x2520) is a family of precision, delta-sigma (ΔΣ) modulators 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 7000 VPK according to t.
