Description
The CS4383 is a complete 8-channel digital-to-analog
system including digital interpolation, fifth-order delta-
sigma digital-to-analog conversion, digital de-emphasis,
volume control and 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 CS4383 accepts PCM data at sample rates from
4 kHz to 192 kHz, DSD audio data, and operates over a
wide power supply range. These features are ideal for
multi-channel audio systems including DVD players,
SACD players, A/V receivers, digital TV’s and VCR’s,
mixing consoles, effects processors, set-top boxes, and
automotive audio systems.

Notes: 5. VFS is tested under load RL and includes attenuation due to ZOUT
6. Current consumption increases with increasing FS within a given speed mode and is signal dependant.
Max values are based on highest FS and highest MCLK.
7. ILC measured with no external loading on the SDA pin.
8. This specification is violated when the VLC supply is greater than VD and when pin 16 (M1/SDA) is tied
or pulled low. Logic tied to pin 16 needs to be able to sink this current.
9. Power down mode is defined as RST pin = Low with all clock and data lines held static.
10. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figures 5 and 6.

Notes: 22. tspi only needed before first falling edge of CS after RST rising edge. tspi = 0 at all other times.
23. Data must be held for sufficient time to bridge the transition time of CCLK.
