DESCRIPTION
The AMC1210 is a four-channel digital filter designed specifically for current measurement and resolver position decoding in motor control applications. Each input can receive an independent delta-sigma (ΔΣ) modulator bit stream. The bit streams are processed by four individually-programmable digital decimation filters. The AMC1210 also offers a flexible interface and a comprehensive interrupt unit, allowing customized digital functionality and immediate digital threshold comparisons for over-current monitoring.
