The flagship CS3318 is an eight-channel, high-voltage, digitally controlled analog volume control IC that is the benchmark for audio quality, showcasing 127 dB dynamic range.
The CS3318 operates from a ±9 V power supply, with 118 dB adjustable range from +22dB to -96dB, negligible distortion and inter-channel isolation. Plus, a 0.25 dB step size with zero-crossing detection and programmable time out ensures remarkably smooth control of volume adjustment. The CS3308 is a pin-compatible ±5 V version with a very high dynamic range of 123 dB.
