LMC835 Digital Controlled Graphic Equalizer
General Description
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 g12 dB or g6
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 distor-
tion resulting in very high performance compatible with
PCM audio
