1.3 Description
The TLV320DAC3120 is a low-power, highly
integrated, high-performance mono DAC with 24-bit
mono playback.
The device integrates several analog features, such
as a microphone bias, headphone drivers, and a
mono speaker driver capable of driving a 4-Ω load.
The TLV320DAC3120 has a fully programmable
miniDSP for digital audio processing. The digital
audio data format is programmable to work with
popular audio standard protocols (I²S,
left/right-justified) in master, slave, DSP, and TDM
modes. Bass boost, treble, or EQ can be supported
by the programmable digital-signal processing block.
An on-chip PLL provides the high-speed clock
needed by the digital signal-processing block. The
volume level can be controlled by either a pin control
or by register control. The audio functions are
controlled using the I²C serial bus.
The TLV320DAC3120 is available in a 32-pin QFN
package.
