CS4228

24-Bit, 96 kHz Surround Sound Codec

Features

Description

The CS4228 codec provides two analog-to-digital and

six digital-to-analog delta-sigma converters, along with

volume controls, in a compact +5/+3.3 V, 28-pin SSOP

device. Combined with an IEC958 (SPDIF) receiver (like

the CS8414) and surround sound decoder (such as one

of the CS492x or CS493xx families), it is ideal for use in

DVD player, A/V receiver and car audio systems sup-

porting multiple standards such as Dolby Digital AC-3,

AAC, DTS, Dolby ProLogic, THX, and MPEG.

- 102 dB dynamic range

- 90 dB THD+N

l Six 24-bit D/A Converters

- 103 dB dynamic range and SNR

- 90 dB THD+N

l Sample rates up to 100 kHz

l Pop-free Digital Output Volume Controls

- 90.5 dB range, 0.5 dB resolution (182 levels)

- Variable smooth ramp rate, 0.125 dB steps

l Mute Control pin for off-chip muting circuits
