Product Summary

The 3310-KSZ is a complete stereo digital volume control designed specifically for audio systems. It features a 16-bit serial interface that controls two independent, lowdistortion audio channels. The 3310-KSZ 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 3310-KSZ for multi-channel audio systems. The 3310-KSZ operates from ±5 V supplies and has an input/output voltage range of ±3.75 V.
