Overview
CS4354 5-V Stereo DAC with 2-VRMS Ground-Centered Output Features Description  Advanced multibit delta–sigma modulator  101 dB A-weighted dynamic range  –86 dB THD+N  Single-ended ground-centered analog architecture – No DC-blocking capacitors required – Integrated inverting charge pump – Filtered line-level outputs – 2 VRMS full-scale output  Low-latency digital filtering  Supports sample rates up to 192 kHz  24-bit I²S input  +5-V analog supply with integrated inverting charge pump and regulator for core logic, and +1.
8-V to +5-V interface power supplies  50-mW power consumption  14-pin SOIC, lead-free assembly The CS4354 is a complete stereo digital-to-analog system including digital interpolation, third-order multi-bit delta–sigma digital-to-analog conversion, digital de-emphasis, analog filtering, and on-chip 2 VRMS line-level driver from a 5 V supply.
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.
These features are ideal for cost-sensitive, two-channel audio systems including video game consoles, Blu-Ray Disc® and DVD players, set-top boxes, digital TVs, and DAB/DMB devices.
The CS4354 is available in a 14-pin SOIC package in Commercial (–40°C to +85°C) grade.
The CDB4354 Customer Demonstration Board is also available for device evaluation and implementation suggestions.
