CS4350

Description

The CS4350 is a complete stereo digital-to-analog system including PLL-based master clock derivation, digital in-

terpolation, 5th-order multi-bit delta-sigma digital-to-analog conversion, digital de-emphasis, volume control,

channel mixing, and analog filtering. The advantages of this architecture include ideal differential linearity, no dis-

tortion mechanisms due to resistor matching errors, no linearity drift over time and temperature, high tolerance to

clock jitter, and a minimal set of external components.

The CS4350 supports all standard digital audio interface formats, including TDM.

The CS4350 is available in a 24-pin TSSOP package in both Commercial (-40° to +85°C) and Automotive grades

(-40° to +105°C). The CDB4350 Customer Demonstration board is also available for device evaluation and imple-

mentation suggestions. Please refer to “Ordering Information” on page 40 for complete ordering information.

These features are ideal for cost-sensitive, two-channel audio systems, including DVD players and recorders, set-

top boxes, digital TVs, mini-component systems, mixing consoles and automotive audio systems.
