PRODUCT OVE RVIE W
T he AD1816A SoundPort Controller is a single chip Plug and
Play multimedia audio subsystem for concurrently processing
multiple digital streams of 16-bit stereo audio in personal com-
puters. T he AD1816A maintains full legacy compatibility with
applications written for SoundBlaster Pro and AdLib, while ser-
vicing Microsoft PC 97 application requirements. T he AD1816A
includes an internal OPL3 compatible music synthesizer, Phat
Stereo circuitry for phase expanding the analog stereo output,
an MPU-401 UART , joystick interface with a built-in timer, a
DSP serial port and two I
2
S serial ports. T he AD1816A on-chip
Plug and Play routine provides configuration services for all in-
tegrated logical devices. Using an external E
2
PROM allows the
AD1816A to decode up to two additional external user-defined
logical devices such as modem and CD-ROM.
