Overview
The LA7451M is a two-channel, noise reduction processor IC for 8-mm video recorder, pulse code modulation (PCM) circuits.
The LA7451M incorporates two filters, on per channel, comprising emphasis circuits, weighting compensators, voltage-controlled amplifiers (VCA) and detectors. Filter control circuitry sets the emphasis and weighting of each filter.
The LA7451M operates from a 4.75V supply and is available in 30-pin MFPs.
