and Level Control

• Microphone Bias

• Built-in Digital Audio Processing Blocks With

User-Programmable Biquad, FIR Filters, and

DRC

• Programmable Digital Audio Processor for

Bass Boost/Treble/EQ With up to Six Biquads

for 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

(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.

• Integrated PLL Used for Programmable Digital

TDM Audio Interfaces

• I²C Control With Register Auto-Increment

• Full Power-Down Control

• Power Supplies:

– Analog: 2.7 V–3.6 V

The TLV320DAC3120 is available in a 32-pin QFN

package.

– Digital Core: 1.65 V–1.95 V

– Digital I/O: 1.1 V–3.6 V

– Class-D: 2.7 V–5.5 V (SPKVDD ≥ AVDD)

• 5-mm × 5-mm 32-QFN Package
