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. Both the CS3318 and CS3308 serve to reduce external component count and reduce printed circuit board space, helping OEMs achieve more compact products at lower cost. Applications
