Up to 192 kHz Sample Rates ! 112 dB Dynamic Range ! -100 dB THD+N ! +3.3 V, +9 to 12 V, and VL Power Supplies ! 2 Vrms Output into 5 k Ω AC Load ! Digital Volume Control with Soft Ramp – 119 dB Attenuation – 1/2 dB Step Size – Zero Crossing Click-Free Transitions ! ATAPI Mixing ! Low Clock Jitter Sensitivity ! Popguard® Technology for Control of Clicks and Pops 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 for complete details. 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.
