Overview
The AD1815JS is a SoundComm controller from Analog Devices, designed as a single-chip Plug and Play audio subsystem. It integrates stereo audio and communications support for personal computers, compatible with SoundBlaster Pro and AdLib/OPL3 applications. The device features a 16-bit SD codec, an integrated V.34 modem analog front end, and a serial port for DSP linking. Operating on a +5V supply (4.75V to 5.25V), it supports full-duplex capture and playback at multiple sample rates simultaneously. Key interfaces include I2S digital audio inputs and an MPU-401 compatible MIDI port.
Feature Summary
- Integrated 16-bit stereo audio codec with MPC Level-2/3 mixer
- Built-in V.34 compatible modem analog front end
- Supports up to six different sample rates simultaneously
- MPU-401 compatible MIDI port and enhanced digital game port
Applications
- Personal computer audio subsystems
- Windows 95 and Windows 3.1 multimedia applications
- Telephony and voice over data systems
- DirectSound compatible audio hardware
Procurement Notes
Verify the 100-PQFP package dimensions and pinout against the official datasheet before PCB layout. Confirm that the specific JS suffix variant meets the required operating temperature range of 0°C to 70°C. Ensure compatibility with existing ISA bus architectures if integrating into legacy systems.
Selection Notes
Select this component for designs requiring a unified audio and modem solution in a single package. It is suitable for applications needing simultaneous multi-rate sampling and software-controlled volume management. Consider the 100-pin BQFP footprint constraints during mechanical design.
Part Context
The AD1815 belongs to the SoundComm series, providing an integrated solution for PC audio and communication needs. It replaces discrete codec and modem frontend components, simplifying board design for multimedia PCs and telephony devices.
Replacement Considerations
Check for direct pin-compatible upgrades within the AD18xx series. Verify backward compatibility with SoundBlaster Pro drivers if replacing older audio controllers.
