ES1946 Solo-1E™ PCI AudioDrive® Notebook Solution Data Sheet DESCRIPTION The ES1946 Solo-1E™ PCI AudioDrive® solution implements a single-chip PCI audio solution, providing high-quality audio processing while maintaining full legacy DOS game compatibility. With a dynamic range over 80 dB, the ES1946 complies with the Microsoft® PC 97 / PC 98 / PC 99 specifications and meets WHQL audio requirements. The ES1946 forms a complete audio subsystem on a single chip for notebook platforms. The ES1946 includes an I2S Zoom Video port interface which allows playback of MPEG audio using the 16-bit stereo music DAC; thus reducing the total audio solution chip count.
