CS4391

24-Bit, 192 kHz Stereo DAC with Volume Control

Features

Description

The CS4391 is a complete stereo digital-to-analog sys-

tem including digital interpolation, fourth-order delta-

sigma digital-to-analog conversion, digital de-emphasis,

volume control, channel mixing and analog filtering. The

advantages of this architecture include: ideal differential

linearity, no distortion mechanisms due to resistor

matching errors, no linearity drift over time and tempera-

ture and a high tolerance to clock jitter.

l Complete Stereo DAC System: Interpolation,

D/A, Output Analog Filtering

l 108 dB Dynamic Range

l 94 dB THD+N

l Direct Stream Digital Mode

l Low Clock Jitter Sensitivity

l +5 V to +3 V Power Supply

l ATAPI Mixing

l On-Chip Digital De-emphasis for 32, 44.1,

and 48 kHz

l Volume Control with Soft Ramp

– 119 dB Attenuation

The CS4391 accepts PCM data at sample rates from

2 kHz to 192 kHz, DSD audio data, consumes very little

power and operates over a wide power supply range.

These features are ideal for DVD, A/V receivers, CD and

set-top box systems.

– 1 dB Step Size

– Zero Crossing Click-Free Transitions

l 36 mW with 3 V supply
