The ES1869 AudioDrive solution is a single, mixed-signal chip that adds 16-bit stereo sound and FM music synthesis to personal computers. It is compliant with the Microsoft PC 97 and PC 98 specifications and WHQL audio requirements. The ES1869 possesses an embedded microcontroller, an OPL3TM superset ESFMTM music synthesizer, a 16-bit stereo wave ADC and DAC, 16bit stereo music DAC, MPU-401 UART mode serial port, dual game port, full plug-and-play support, CD-ROM IDE interface, hardware master volume control, two serial port interfaces to external DSP and external wavetable music synthesizer, I2S zoom video interface, DMA control logic with FIFO, and ISA bus interface logic. There are three stereo inputs (typically line, CD audio, and auxiliary line) and a mono microphone input. This single chip can be designed into a motherboard, and add-on card, or integrated into other peripheral cards such as Fax/Modem, VGA, LAN, I/O, etc.
