Description
The CS3318 is an 8-channel digitally controlled analog
volume control designed specifically for high-end audio
systems. It features a comprehensive IC/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.
The IC/SPI control interface provides for easy system
integration of up to 128 CS3318 devices over a single 2-
wire IC 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.
The device operates from ±8 V to ±9 V analog supplies
and has an input/output voltage range of ±6.65 V to
±7.65 V. The digital control interface operates at +3.3 V.
The CS3318 is available in a 48-pin LQFP package in
Commercial grade (-10° to 70° C). The CS3318 Cus-
tomer Demonstration board is also available for device
evaluation. Refer to “Ordering Information” on page 44
for complete details.
