Description
The CS4382 is a complete 8-channel digital-to-analog
system including digital interpolation, fifth-order delta-
sigma digital-to-analog conversion, digital de-empha-
sis, 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 CS4382 is available in a 48-pin LQFP package in
Commercial grade (-10°C to +70°C). The CDB4382
Customer Demonstration Board is also available for de-
vice evaluation and implementation suggestions.
Please see
plete details.
The CS4382 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, mixing con-
soles, effects processors, and automotive audio
systems.

    ... PCM Mode Select The CS4382 operates in one of three PCM oversampling modes based on the input sample rate. Mode se- lection is determined by the M3 and M2 pins in Stand-Alone Mode or the FM bits in Control Port Mode. Sin- gle-Speed Mode supports input sample rates kHz and uses a 128x oversampling ratio. Double- Speed Mode supports input sample rates up to 100 kHz and uses an oversampling ratio of 64x ...

    ... The CS4382 has MAP auto increment capability, enabled by the INCR bit in the MAP register, which is the MSB. If INCR is 0, then the MAP will stay constant for successive writes. If INCR is set to 1, then MAP will auto increment after each byte is written from register 01h to 08h and then from 09h and 11h, allowing block reads or writes of suc- cessive registers in two separate sections (the counter will not auto-increment to register 09h from register 08h) ...

    ... The control port has 2 formats: SPI and I²C, with the CS4382 operating as a slave device. If I²C operation is desired, AD0/CS should be tied to VLC or GND. If the CS4382 ever detects a high to low transition on AD0/CS after power-up and after the control port is activated, SPI format will be selected. ...
