Parallel-Port 16-Bit  
SoundPort® Stereo Codec  
a
AD1845  
FEATURES  
plete on-chip filtering, MPC Level-2 compliant analog mixing,  
programmable gain, attenuation and mute, a variable sample  
frequency generator, FIFOs, and supports advanced power-  
down modes. It provides a direct, byte-wide interface to both  
ISA (“AT ”) and EISA computer buses for simplified implemen-  
tation on a computer motherboard or add-in card.  
Single-Chip Integrated ∑∆ Digital Audio Stereo Codec  
Microsoft® and Window s® Sound System Com patible  
MPC Level-2+ Com pliant Mixing  
16 m A Bus Drive Capability  
Supports Tw o DMA Channels for Full Duplex Operation  
On-Chip Capture and Playback FIFOs  
Advanced Pow er-Dow n Modes  
Program m able Gain and Attenuation  
Sam ple Rates from 4.0 kHz to 50 kHz Derived from a  
Single Clock or Crystal Input  
68-Lead PLCC, 100-Lead TQFP Packages  
Operation from +5 V Supplies  
Byte-Wide Parallel Interface to ISA and EISA Buses  
Pin Com patible w ith AD1848, AD1846, CS4248, CS4231  
T he AD1845 SoundPort Stereo Codec supports a DMA re-  
quest/grant architecture for transferring data with the host com-  
puter bus. One or two DMA channels can be supported.  
Programmed I/O (PIO) mode is also supported for control  
register accesses and for applications lacking DMA control.  
T wo input control lines support mixed direct and indirect ad-  
dressing of thirty-seven internal control registers over this asyn-  
chronous interface. T he AD1845 includes dual DMA count  
registers for full duplex operation enabling the AD1845 to cap-  
ture data on one DMA channel and play back data on a separate  
channel. T he FIFOs on the AD1845 reduce the risk of losing  
data when making DMA transfers over the ISA/EISA bus. T he  
FIFOs buffer data transfers and allow for relaxed timing in  
acknowledging requests for capture and playback data.  
P RO D UCT O VERVIEW  
T he Parallel Port AD1845 SoundPort Stereo Codec integrates  
key audio data conversion and control functions into a single  
integrated circuit. T he AD1845 provides a complete, single chip  
computer audio solution for business audio and multimedia  
applications. T he codec includes stereo audio converters, com-
