GENERAL DESCRIPTION

The AD1838A is a high performance single-chip codec featuring

three stereo DACs and one stereo ADC. Each DAC comprises a

high performance digital interpolation filter, a multibit ꢀ-ꢁ

modulator featuring Analog Devices’ patented technology,

and a continuous-time voltage out analog section. Each DAC

has independent volume control and clickless mute functions.

The ADC comprises two 24-bit conversion channels with

multibit ꢀ-ꢁ modulators and decimation filters.

DACs: –95 dB THD + N, 108 dB SNR and

Dynamic Range

On-Chip Volume Controls per Channel with

1024 Step Linear Scale

The AD1838A also contains an on-chip reference with a nomi-

nal value of 2.25 V.

DAC and ADC Software Controllable Clickless Mutes

Digital De-emphasis Processing

Supports 256 ꢂ f_S, 512 ꢂ f_S, and 768 ꢂ f_SMaster

Mode Clocks

Power-Down Mode Plus Soft Power-Down Mode

Flexible Serial Data Port with Right-Justified, Left-

Justified, I²S Compatible, and DSP Serial Port Modes

TDM Interface Mode Supports 8 In/8 Out Using a

Single SHARC^®SPORT

The AD1838A contains a flexible serial interface that allows

glueless connection to a variety of DSP chips, AES/EBU

receivers, and sample rate converters. The AD1838A can be

configured in left-justified, right-justified, I²S, or DSP com-

patible serial modes. Control of the AD1838A is achieved by

means of an SPI^®compatible serial port. While the AD1838A

can be operated from a single 5 V supply, it also features a sepa-

rate supply pin for its digital interface that allows the device to

be interfaced to other devices using 3.3 V power supplies.

52-Lead MQFP Plastic Package

The AD1838A is available in a 52-lead MQFP package and is

specified for the industrial temperature range of –40ºC to +85ºC.
