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 fS, 512 fS, and 768 fS Master  
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.
