The LMC835 is a monolithic digitally-controlled graphic equalizer CMOS LSI for Hi-Fi audio The LMC835 consists of a Logic section and a Signal Path section made of analog switches and thin-film silicon-chromium resistor networks The LMC835 is used with external resonator circuits to make a stereo equalizer with seven bands g 12 dB or g 6 dB gain range and 25 steps each Only three digital inputs are needed to control the equalization The LMC835 makes it easy to build a mP-controlled equalizer The signal path is designed for very low noise and distortion resulting in very high performance compatible with PCM audio
