SoundPort Stereo Codec  
AD1849K  
FEATURES  
(mono) speaker and stereo headphone drive circuits that require  
no additional external components. Dynamic range exceeds  
80 dB over the 20 kHz audio band. Sample rates from 5.5 kHz  
to 48 kHz are supported from external crystals, from an external  
clock, or from the serial interface bit clock.  
Single-Chip Integrated ⌺⌬ Digital Audio Stereo Codec  
Multiple Channels of Stereo Input and Output  
Digital Signal Mixing  
On-Chip Speaker and Headphone Drive Capability  
Programmable Gain and Attenuation  
On-Chip Signal Filters  
Digital Interpolation and Decimation  
Analog Output Low-Pass  
Sample Rates from 5.5 kHz to 48 kHz  
44-Lead PLCC Package  
The Codec includes a stereo pair of Σ∆ analog-to-digital converters  
and a stereo pair of Σ∆ digital-tonalog converters. Analog signals  
can be input at line levels omicropone levels. A software  
controlled programmable stagallows independent gain for  
each channel going intthe AThe ADs’ output can be  
digitally mixed with e DACs’ ut.  
Operation from 5 V and Mixed 5 V/3.3 V Supplies  
Serial Interface Compatible with ADSP-21xx Fixed-  
Point DSPs  
The left and rigchnel 16-bit oputs from the ADCs are  
available over a single bectional serial interface that also sup-  
ports 16-bdigital input te DACs and control information.  
The AD849K can accept and generate 8-bit µ-law or A-law  
compded dital data.  
Compatible with CS4215 (See Text)  
PRODUCT OVERVIEW  
The Serial-Port AD1849K SoundPort Stereo Codec integrates  
the key audio data conversion and control functions into a single  
integrated circuit. The AD1849K is intended to provide a com-  
plete, single-chip audio solution for multimedia applications  
requiring operation from a single 5 V supply. External signal  
path circuit requirements are limited to three low toler
capacitors for line level applications; anti-imaging fi
incorporated on-chip. The AD1849K includes on-chip
The Σ∆ s are preded by a digital interpolation filter. An  
attenuator vidindependent user volume control over each  
DAC channel. yquist images and shaped quantization noise  
are removed from the DACs’ analog stereo output by on-chip  
itched-pacitor and continuous-time filters. Two independent  
steirs of line-level (or one line-level and one headphone)  
outputs are generated, as well as drive for a monaural speaker.
