Stereo Digital Volume Control CS3310
The CS3310 is a complete stereo digital volume control designed specifically for audio systems. It features a 16-bit serial interface that controls two independent, low-distortion audio channels. The CS3310 includes an array of well-matched resistors and a low-noise active output stage that is capable of driving a 600 ω load. A total adjustable range of 127 dB, in 0.5 dB steps, is achieved through 95.5 dB of attenuation and 31.5 dB of gain. The simple 3-wire interface provides daisy-chaining of multiple CS3310s for multichannel audio systems. The device operates from ±5 V supplies and has an input/output voltage range of ±3.75 V. Features Complete digital volume control Two independent channels Serial control 0.5 dB step size Wide adjustable range -95.5 dB attenuation +31.5 dB gain Low distortion and noise -100 THD+N 116 dB dynamic range Noise-free level transitions Channel-to-channel crosstalk better than 110 dB Package: 16-pin plastic SOIC; lead-free assembly
