1-1 Introduction
Introduction
The DAC26 is a low-power, high-performance audio band DAC with dual or
stereo output. The DAC26 has two digital interface buses that communicate
with a host processor: the SPI interface and the I
2
S interface. The SPI serial
interface is for a host processor to control the DAC26, and the DAC data is
communicated to the DAC26 over the I
2
S bus. The DAC26 accesses both of
these buses through the use of a USB microcontroller, which provides a way
to generate data for both buses from a PC running Windows
r
98, Windows
2000, or Windows XP.
