Cirrus Logic CS3308-CQZ

音量控制音频系统8I²C，SPI4.75V ~ 5.25V

Overview

Cirrus Logic’s 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 +22 dB to -96 dB, 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-CQZ is a pin-compatible ±5 V version with a very high dynamic range of 123 dB. Both the CS3318 and CS3308-CQZ serve to reduce external component count and reduce printed circuit board space, helping OEMs achieve more compact products at lower cost. Patent-pending technologies such as dynamic address assignment and simultaneous master volume controls across multiple devices over a single serial control bus simplifies designs and further reduces costs.
