CS4351-DZZ Datasheet PDF - Cirrus Logic

Description
The CS4351 is a complete stereo digital-to-analog system including digital interpolation, fifth-order multi-bit delta-sigma digital-to-analog conversion, digital de-emphasis, 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 tolerance 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 evaluation 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.
