Description
The CS4360 is a complete 6-channel digital-to-analog
system including digital interpolation, fourth-order delta-
sigma digital-to-analog conversion, digital de-emphasis,
volume control, channel mixing 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 tempera-
ture, and a high tolerance to clock jitter.
The CS4360 accepts data at audio sample rates from
4 kHz to 200 kHz, consumes very little power, and oper-
ates over a wide power supply range. These features are
ideal for cost-sensitive, multi-channel audio systems in-
cluding DVD players, A/V receivers, set-top boxes,
digital TVs and VCRs, mini-component systems, and
mixing consoles.
