Description
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 load. A total adjustable range of 127 dB,
in 0.5 dB steps, is achieved through 95.5 dB of attenua-
tion and 31.5 dB of gain.
The simple 3-wire interface provides daisy-chaining of
multiple CS3310's for multi-channel audio systems.
The device operates from ±5 V supplies and has an in-
put/output voltage range of ±3.75 V.
