CS5381

120 dB, 192 kHz, Multi-Bit Audio A/D Converter

Features

General Description

! Advanced Multi-bit Delta-Sigma Architecture

! 24-bit Conversion

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.

! 120 dB Dynamic Range

! -110 dB THD+N

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.

! Supports All Audio Sample Rates Including

192 kHz

! 260 mW Power Consumption

! High-Pass Filter or DC Offset Calibration

! Supports Logic Levels between 5 and 2.5 V

! Differential Analog Architecture

! Low-Latency Digital Filtering

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.

! Overflow Detection

! Pin-Compatible with the CS5361

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.
