The CS4340 is a complete stereo digital-to-analog (D/A) system including digital interpolation, fourth-order Delta-Sigma D/A 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 2 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 boxes, and automotive systems.


  • Complete stereo D/A converter system: interpolation, D/A, output analog filtering
  • 101 dB dynamic range
  • -91 dB THD+N
  • Low clock-jitter sensitivity
  • Filtered line-level outputs
  • On-chip digital de-emphasis for 32 kHz, 44.1 kHz, and 48 kHz
  • 3.3 V or 5 V power supply
  • 30 mW with 3 V supply
  • Popguard® technology for control of clicks and pops
  • Pin-compatible with CS4340A
  • Package: 16-pin SOIC, 16-pin TSSOP; lead-free assembly
