AMC1204BDWR Integrated Circuit Chip
20MHz Isolated Delta-Sigma Modulator in SOIC16 Package
Product Overview
The AMC1204BDWR is a 1-bit digital output, isolated delta-sigma (ΔΣ) modulator that can be clocked at up to 20 MHz. The digital isolation of the modulator output is provided by a silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference.
This device provides a single-chip solution for measuring small signals across shunt resistors in isolated barrier applications. These resistors are commonly used for current sensing in motor control inverters, green energy generation systems, and various industrial applications.
