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 onTDM

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.
