OVERVIEW
The TLV320DAC26 is a highly integrated stereo audio DAC for portable computing, communication, and entertainment
applications. The ’DAC26 has a register-based architecture where all functions are controlled through the registers and
onboard state machines.
The ’DAC26 consists of the following blocks (refer to the block diagram):
Audio DAC
Auxiliary Inputs for analog pass through functionality
Audio data is transferred between the host DSP/
μ
P via a standard 4-wire interface and supports a variety of modes (i.e.,
I
2
S, DSP, etc).
Control of the ’DAC26 and its functions is accomplished by writing to different registers in the ’DAC26. A simple command
protocol is used to address the 16-bit registers. Registers control the operation of the audio DAC. The control and auxiliary
functions are accessed via a SPI bus.
A typical application of the ’DAC26 is shown in Figure 8.
