Description

The CS4362 is a complete 6-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 CS4362 is available in a 48-pin LQFP package in

Commercial grade (-10°C to +70°C). The CDB4362

Customer Demonstration Board is also available for de-

vice

evaluation

and

implementation

suggestions.

Please see “Ordering Information” on page 42 for com-

plete details.

The CS4362 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, and effects processors.
