Description

The CS4351 is a complete stereo digital-to-analog sys-

tem including digital interpolation, fifth-order multi-bit

delta-sigma digital-to-analog conversion, digital de-em-

phasis, volume control, channel mixing, analog filtering,

and on-chip 2 Vrms line-level driver. The advantages of

this architecture include ideal differential linearity, no

distortion mechanisms due to resistor matching errors,

no linearity drift over time and temperature, high toler-

ance to clock jitter, and a minimal set of external

components.

The CS4351 is available in a 20-pin TSSOP package in

both Commercial (-10°C - +70°C) and Automotive

grades (-40°C to +85°C). The CDB4351 Customer

Demonstration board is also available for device evalu-

ation and implementation suggestions. Please see

“Ordering Information” on page 37

These features are ideal for cost-sensitive, 2-channel

audio systems including DVD players, A/V receivers,

set-top boxes, digital TVs and VCRs, mini-component

systems, and mixing consoles.
