LMF120 Overview
The LMF120 is a mask-programmable switched-capacitor filter capable of realizing virtually any filter response up to twelve poles using six independent biquad blocks. It is customized to meet specific application requirements through the use of automated design techniques. Circuit realization occurs during the final metal-mask stage of the manufacturing process.
