TLV320AIC3106IRGZT - Low-Power Stereo Audio CODEC | TI
MPN: TLV320AIC3106IRGZT ✓ Hoạt độngTLV320AIC3106IRGZT Tóm tắt
An audio CODEC (coder-decoder) is an integrated circuit that converts between digital audio streams and analog microphone/line/headphone signals, combining an ADC input path and DAC output path inside a single chip. The TLV320AIC3106 sits in the broader hierarchy of audio interface ICs -> interface ICs -> integrated circuits, and is widely deployed in portable, battery-powered, and space-constrained designs where low power, stereo playback, and integrated headphone drive are required simultaneously. Multiple line, microphone, and headphone amplifiers share an extensive register-based power-control interface, enabling fine-grained energy management as system use cases change.
Key features of the TLV320AIC3106 include stereo 24-bit ADC and DAC with 102 dBA SNR, integrated 40 mW headphone amplifier, programmable 3D / bass / treble / EQ digital effects, and selectable single-ended or fully-differential analog inputs. The digital serial audio bus supports I2S, left-justified, right-justified, and DSP/PCM modes for flexible connection to virtually any application processor or DSP. An automatic gain control (AGC) block on the ADC path keeps microphone levels stable across varying speech distances.
At the architectural level the device pairs a multi-bit delta-sigma modulator front end with on-chip FIR and IIR engine blocks so that tone control, EQ, and de-emphasis are applied digitally without burdening the host processor. PLL-based clock generation accepts common 12, 13, 24, or 27 MHz system clocks and derives all internal timing from them, simplifying board layout by removing the need for a dedicated audio master crystal in many designs. Extensive register-based power control keeps unused analog blocks powered down until audio paths are activated.
Typical applications span portable media players, portable navigation devices, mobile phones and VoIP handsets, portable gaming, digital still cameras and camcorders, ultrasonic imaging, IP phones and USB headsets, as well as portable audio docks and Bluetooth speakers. The combination of low power, integrated headphone drive, and rich on-chip digital effects makes it equally suitable for stereo playback and full-duplex voice-capture products.
When designing with this part, ensure both the 1.8 V digital and 3.3 V analog rails are well decoupled close to the IC, and that the PLL reference clock is selected to match the chosen MCLK frequency in software. Because the device supports both single-ended and differential microphone paths, designers should populate the unused input pins according to the datasheet reference circuit rather than leaving them floating.

Ứng dụng tiêu biểu
TLV320AIC3106IRGZT phù hợp cho 6 Áp dụngs: Portable Media Player Audio CODEC Path, Mobile Phone and VoIP Handset Audio Interface, USB Audio Headset and Dongle, IP Phone and VoIP Speakerphone, Portable Navigation Device (PND) Audio, Digital Camera and Camcorder Audio Capture.
Portable Media Player Audio CODEC Path
The TLV320AIC3106IRGZT is well suited to portable media player (PMP) designs where stereo 44.1 kHz or 48 kHz DAC playback drives 16 ohm / 32 ohm headphones from a 3.3 V analog rail. The 102 dBA DAC SNR preserves dynamic range for lossless FLAC playback, while the integrated 40 mW headphone amplifier removes the need for an external line-driver stage, reducing BOM cost and PCB area. Designers typically route I2S BCLK / WCLK / DIN from the host application processor and let the on-chip PLL synthesize all internal clocks from a 12 MHz or 13 MHz system reference, eliminating a dedicated audio master crystal.

Mobile Phone and VoIP Handset Audio Interface
The TLV320AIC3106IRGZT serves as the main audio CODEC in mobile phones and VoIP handsets, providing simultaneous stereo ADC capture (for dual-mic noise cancellation) and stereo DAC playback (for earpiece and loudspeaker paths) from a single chip. The differential microphone input paths reject handset-mode common-mode noise, while the on-chip AGC block maintains consistent voice levels even when users speak at varying distances. Its low 15 mW stereo playback power from a 3.3 V supply extends battery life in always-on voice standby use cases, and the I2C / I2S digital interface ties cleanly into most application processors and baseband modems.
Được đề xuất
USB Audio Headset and Dongle
The TLV320AIC3106IRGZT is frequently paired with a USB audio bridge IC in USB headsets, where it performs the analog-to-digital capture and digital-to-analog playback functions at the headset end of the cable. Its stereo headphone amplifier directly drives 32 ohm headset drivers without external buffers, and the integrated microphone preamps accommodate both legacy single-ended ECM and modern differential MEMS microphones. The 16/20/24/32-bit data path with 8-96 kHz sample support matches all common USB audio class 1.0 / 2.0 profiles.
Được đề xuất
IP Phone and VoIP Speakerphone
The TLV320AIC3106IRGZT powers full-duplex IP phones and conference speakerphones by handling the analog microphone capture for the far-end uplink and the analog downlink to the handset / speaker amplifier. Its on-chip 3D / bass / EQ effects and 5-band parametric equalizer shape the speakerphone frequency response without burdening the DSP host, and the selectable differential inputs reject the common-mode hum that plagues desktop phones connected to building wiring. The 3.3 V analog supply is straightforward to generate from a typical 5 V or 12 V PoE rail, simplifying the power tree.
Được đề xuất
Portable Navigation Device (PND) Audio
PND designs use the TLV320AIC3106IRGZT to deliver clear voice prompts and stereo music playback simultaneously through the device's built-in speaker or headphone jack. The CODEC handles turn-by-turn voice prompts on the DAC path while capturing voice for hands-free Bluetooth bridge or voice command through the same ADC path. Low standby power consumption preserves battery life for handheld car-mount use, and the wide operating temperature range (-40 C to +85 C) survives the harsh automotive cabin environment.
Được đề xuất
Digital Camera and Camcorder Audio Capture
Digital still cameras and camcorders use the TLV320AIC3106IRGZT to capture stereo audio alongside HD video, where its 95 dBA ADC SNR preserves the dynamic range required for music or speech recording. The compact 7x7 mm VQFN-48 package fits alongside image sensor PCBs in space-constrained camera bodies, and the integrated microphone preamps remove the need for a separate audio ADC board. Differential microphone inputs reject camera body noise and motor EMI from the autofocus and zoom mechanisms, giving cleaner recordings in real-world handheld shooting conditions.

Ghi chú thiết kế
Estimated: at 3.3 V analog, 1.8 V digital, and stereo 48 kHz DAC playback, the TLV320AIC3106IRGZT draws approximately 15 mW per the datasheet headline figure. Decouple AVDD, DVDD, MICBIAS_PWR, and PLL_VDD locally with 10 uF ceramic plus 0.1 uF high-frequency caps placed within 2 mm of each pin; inadequate decoupling on the PLL supply is a common cause of periodic clicking artifacts in the DAC output.
Keep AGND and DGND separated on the PCB and tie them together at a single point near the exposed thermal pad to avoid ground loops that inject hum into the high-impedance microphone paths. Route the MCLK line as a short, matched trace surrounded by ground to keep edge rates fast without radiating EMI; if MCLK exceeds 50 MHz, treat it as a controlled-impedance line.
Do not leave the MICBIAS output floating - always load it with the selected microphone impedance per the datasheet's biasing chart, otherwise supply ripple couples directly into the ADC path. For differential headphone drive, both HPLOUT and HPROUT must be AC-coupled to the load; in single-ended cap-less mode ensure the unused negative output is correctly terminated internally via register setting, otherwise click-and-pop on power-up will be loud.
When the on-chip PLL is used to derive internal clocks from a low-frequency MCLK (e.g., 12 MHz), the PLL_FLT loop-filter components must match the datasheet reference (typically 10 nF and 1 kohm in series-to-ground); incorrect loop-filter values will result in fractional-N spurs that degrade THD+N well below the 102 dBA SNR headline. For the cleanest measured audio performance, supply a clean audio-rate MCLK and bypass the PLL block where possible.
