Description

The CS3318 is an 8-channel digitally controlled analog volume control designed specifically for high-end audio systems. It features a comprehensive I2C/SPI serial control port for easy device and volume configuration.

The CS3318 includes arrays of well-matched resistors and complementary low-noise active output stages. A total adjustable range of 118 dB, in ? dB steps, is spread evenly over 96 dB of attenuation and 22 dB of gain.

The CS3318 implements configurable zero-crossing detection to provide glitch-free volume-level changes.
