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.
