CS3308  
8-Channel Analog Volume Control  
Features  
Description  
 Complete Analog Volume Control  
The CS3308 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.  
–
–
8 Independently Controllable Channels  
3 Configurable Master Volume and Muting  
Controls  
The CS3308 includes arrays of well-matched resistors  
and complementary low-noise active output stages. A  
total adjustable range of 118 dB, in ¼ dB steps, is  
spread evenly over 96 dB of attenuation and 22 dB of  
gain.  
 Wide Adjustable Volume Range  
-96 dB to +22 dB in ¼ dB Steps  
 Low Distortion & Noise  
–
–
–
-112 dB THD+N  
123 dB Dynamic Range  
The CS3308 implements configurable zero-crossing  
detection to provide glitch-free volume-level changes.  
 Noise-Free Level Transitions  
–
Zero-Crossing Detection with  
Programmable Time-Out  
The I²C/SPI control interface provides for easy system  
integration of up to 128 CS3308 devices over a single 2-  
wire I²C or 3-wire SPI bus, allowing many channels of  
volume control with minimal system controller I/O re-  
quirements. Devices may be controlled on an individual  
and grouped basis, simplifying simultaneous configura-  
tion of a group of channels across multiple devices,  
while allowing discrete control over all channels on an  
individual basis.  
 Low Channel-to-Channel Crosstalk  
120 dB Inter-Channel Isolation  
–
 Comprehensive Serial Control Port  
–
–
Supports I²C® and SPITM Communication  
Independent Control of up to 128 Devices  
on a Shared 2-Wire I²C or 3-Wire SPI  
Control Bus  
Supports Individual and Grouped Control of  
all CS3308 Devices on the I²C or SPI  
Control Bus  
The device operates from ±5 V analog supplies and has  
an input/output voltage range of ±3.65 V. The digital  
control interface operates at +3.3 V.  
–
The CS3308 is available in a 48-pin LQFP package in  
Commercial grade (-10° to 70° C). The CS3308 Cus-  
tomer Demonstration board is also available for device  
evaluation. Refer to “Ordering Information” on page 44  
for complete details.
