Features • No volume controls required • Three-wire interface • 14 bands, 25 steps each • ±12 dB or ±6 dB gain ranges • Low noise and distortion • TTL, CMOS logic compatible 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, ±12 dB or ±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 µP-controlled equalizer. The signal path is designed for very low noise and distortion, resulting in very high performance, compatible with PCM audio. Applications • Hi-Fi equalizer • Receiver • Car stereo • Musical instrument • Tape equalization • Mixer • Volume controller
