General Description
The CS5381 is a complete analog-to-digital converter
for digital audio systems. It performs sampling, analog-
to-digital conversion, and anti-alias filtering - generating
24-bit values for both left and right inputs in serial form
at sample rates up to 216 kHz per channel.
The CS5381 uses a 5th-order, multi-bit delta-sigma
modulator followed by digital filtering and decimation,
which removes the need for an external anti-alias filter.
The ADC uses a differential architecture which provides
excellent noise rejection.
The CS5381 is available in 24-pin TSSOP and SOIC
packages for Commercial grade (-10° to +70° C). The
CDB5381 Customer Demonstration board is also avail-
able for device evaluation and implementation
suggestions. Please refer to the
“Ordering Information”
on page 22
.
The CS5381 is ideal for audio systems requiring wide
dynamic range, negligible distortion, and low noise -
such as A/V receivers, DVD-R, CD-R, digital mixing
consoles, and effects processors.
