CS4340
24-Bit, 96 kHz Stereo D/A Converter for Audio
Features
! 101 dB Dynamic Range ! -91 dB THD+N ! +3.0 V or +5.0 V Power Supply ! Low Clock Jitter Sensitivity ! Filtered Line-level Outputs ! On-chip Digital De-emphasis for 32, 44.1 and
48 kHz ! 33 mW with 3V Supply ! Popguard® Technology for Control of Clicks
and Pops ! Lead-free Packaging Available Description
The CS4340 is a complete stereo digital-to-analog system including digital interpolation, fourth-order delta-sigma dig-
I
ital-to-analog conversion, digital de-emphasis and switched capacitor 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 temperature and a high tolerance to clock jitter.
The CS4340 accepts data at audio sample rates from 4 kHz to 100 kHz, consumes very little power, and operates over a wide power supply range. The features of the CS4340 are ideal for DVD players, CD players, set-top box and automotive systems.
