CS4354 Datasheet 5 V Stereo Audio DAC

Manufacturer: Cirrus Logic

General 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.
