CS4340A 24-Bit, 192 kHz Stereo DAC for Audio ! 101 dB Dynamic Range ! -91 dB THD+N ! V or +5 V Power Supply ! 50 mW with V supply ! Low Clock Jitter Sensitivity ! Filtered Line Level Outputs ! On-Chip Digital De-emphasis for kHz ! Technology for Control of Clicks and Pops ! Up to 200 kHz Sample Rates ! Automatic Mode Detection for Sample Rates between 4 and 200 kHz ! Pin Compatible with the CS4340 The CS4340A is a complete stereo digital-to-analog system including digital interpolation, fourth-order deltasigma digital-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 CS4340A accepts data at all standard audio sample rates up to 192 kHz, consumes very little power, operates over a wide power supply range and is pin compatible with the CS4340, as described in section These features are ideal for DVD audio players.
