CS4341
24-Bit, 96 kHz Stereo DAC with Volume Control
Features Description
The CS4341 is a complete stereo digital-to-analog sys-
!101 dB Dynamic Range
tem including digital interpolation, fourth-order Delta-
!-91 dB THD+N
Sigma digital-to-analog conversion, digital de-emphasis
!+3.0 V or +5.0 V Power Supply
and switched capacitor analog filtering. The advantages
!Low Clock-Jitter Sensitivity of this architecture include: ideal differential linearity, no
distortion mechanisms due to resistor matching errors,
!Filtered Line-Level Outputs
no linearity drift over time and temperature and a high
!On-Chip Digital De-Emphasis for 32, 44.1
tolerance to clock jitter.
and 48 kHz
The CS4341 accepts data at audio sample rates from
!ATAPI Mixing
4 kHz to 100 kHz, consumes very little power, and oper-
!Digital Volume Control with Soft Ramp
ates over a wide power supply range. The features of
94 dB Attenuation
the CS4341 are ideal for DVD players, CD players, set-
top box and automotive systems.
