SBAS372A – APRIL 2006 – REVISED OCTOBER 2006
Quad Digital Filter for 2nd-Order Delta-Sigma Modulator
FEATURES
• Four Independently-Programmable Digital
Filters
• Four Window Comparators
• Three Parallel and One Serial Interface
• Comprehensive Interrupt System
• Programmable Input Configuration
• Carrier Frequency Generator for Resolver
Applications
APPLICATIONS
• Current Measurement
• Resolver Decoding
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 (∆Σ)
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.
