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 (âÎ£)

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.
