CS4340A Datasheet | Cirrus Logic

Features ! 101 d B Dynamic Range ! -91 d B THD+N ! +3.3 V or +5 V Power Supply ! 50 m W with 3.3 V supply ! Low Clock Jitter Sensitivity ! Filtered Line Level Outputs ! On-Chip Digital De-emphasis for 44.1 k Hz ! Popguard® Technology for Control of Clicks and Pops ! Up to 200 k Hz Sample Rates ! Automatic Mode Detection for Sample Rates between 4 and 200 k Hz ! Pin patible with the CS4340 Description The CS4340A is a plete 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 k Hz, consumes very little power, operates over a wide power supply range and is pin patible with the CS4340, as described in section 3.1. These features are ideal for DVD audio players.
