Product details
Overview
TLV320AIC3106 from Texas Instruments is a low-power stereo audio CODEC with integrated stereo headphone amplifier, 10 programmable analog inputs (single-ended or differential), and 7 output drivers including fully differential line/headphone outputs. It delivers 102-dBA DAC SNR, 92-dBA ADC SNR, 8–96 kHz sample rate support, and 15-mW stereo 48-kHz playback at 3.3-V analog supply - optimized for portable battery-powered telephony and audio systems.
For engineers reviewing the TLV320AIC3106 datasheet, TLV320AIC3106 pinout, TLV320AIC3106 application, or TLV320AIC3106 equivalent, key selection considerations include its dual-supply architecture (2.7–3.6 V analog, 1.65–1.95 V core), I²C/SPI control bus, I²S/DSP/TDM audio interface modes, AGC-enabled microphone recording path, and ultralow-power analog bypass mode for passive signal pass-through.
Technical Context
The TLV320AIC3106 integrates independent stereo DAC and ADC paths with programmable digital filtering (3D, bass/treble/EQ/de-emphasis), configurable input/output gain stages, and automatic gain control (AGC) with attack/decay tuning (8 ms–1.4 s / 0.05–22.4 s). Its analog front-end supports concurrent analog and digital microphone inputs, programmable MICBIAS (2.0/2.5/DRVDD), and noise-filtering during optical zoom in digital cameras.
It features a highly flexible clock system with an integrated PLL supporting MCLKs from 512 kHz to 50 MHz (including 12/13/16/19.2/19.68 MHz), enabling precise generation of standard audio rates without external oscillators. Power management includes modular block-level control and dedicated ultralow-power analog passthrough mode where most circuitry is powered down while maintaining analog signal path integrity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar stereo audio CODEC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV320AIC3104 | 6-input/6-output variant; lacks MIC3 and mono line output; identical DAC/ADC specs and power profile | Suitable for cost-sensitive designs with fewer analog sources and no mono auxiliary output requirement | Select TLV320AIC3104 when full 10-input capability and MONO_LOP/MONO_LOM are unnecessary |
| TLV320AIC3107 | Includes integrated mono Class-D amplifier (1 W into 8 Ω); same 7-output structure but replaces one line driver with Class-D stage | Targeted at speaker-equipped devices (e.g., smart speakers, conferencing units) requiring local amplification | Choose TLV320AIC3107 only if mono speaker drive is required - not a drop-in replacement due to different output topology |
Compared with TLV320AIC3106, TLV320AIC3104 reduces pin count and BOM cost without sacrificing audio performance, while TLV320AIC3107 trades line-output flexibility for integrated speaker drive - making each alternative suitable only for specific subsystem requirements rather than general substitution.

FAQ
What is the minimum analog supply voltage required for TLV320AIC3106 operation?
The TLV320AIC3106 requires a minimum analog supply voltage of 2.7 V on both AVDD_DAC and DRVDD rails. Operation below this threshold risks undefined behavior in the DAC, ADC, and output drivers. The device is fully specified from 2.7 V to 3.6 V, with typical performance characterized at 3.3 V. Using 2.7 V enables compatibility with deeply discharged Li-ion cells while maintaining functional audio paths in TLV320AIC3106.
Does TLV320AIC3106 support I²S interface in master mode?
Yes, TLV320AIC3106 supports I²S interface in both master and slave modes. In master mode, it generates WCLK and BCLK from its internal PLL, allowing it to drive external DACs, ADCs, or DSPs without requiring a system clock source. Timing specifications for master-mode I²S are documented in Section 8.6 of the SLAS509G datasheet, with setup/hold and delay parameters validated across IOVDD ranges. This capability is integral to TLV320AIC3106's role in self-contained audio subsystems.
How many microphone inputs does TLV320AIC3106 support simultaneously?
The TLV320AIC3106 supports up to three independent analog microphone inputs (MIC1, MIC2, MIC3) with fully differential or single-ended configuration per channel. Each input pair (e.g., MIC1L/MIC1R) can be routed independently to the stereo ADC path, and the device also accepts digital microphone data via GPIO1/GPIO2 pins. All three analog mic channels can operate concurrently with programmable bias and AGC - a capability confirmed in the Device Comparison Table and Feature Description sections of the TLV320AIC3106 datasheet.
What package options are available for TLV320AIC3106?
The TLV320AIC3106 is offered in two RoHS-compliant packages: a 5.00 mm × 5.00 mm, 80-ball MicroStar Junior™ BGA (ZQE suffix) and a 7.00 mm × 7.00 mm, 48-pin VQFN (RGZ suffix). Both packages feature exposed thermal pads that must be soldered to the PCB ground plane for thermal compliance. The ZQE package is used in space-constrained portable designs, while the RGZ variant simplifies assembly and debugging. These options are explicitly listed in the Device Information table of the TLV320AIC3106 datasheet.
Can TLV320AIC3106 operate in analog passthrough mode with zero digital power consumption?
In ultralow-power analog passthrough mode, TLV320AIC3106 powers down its DAC, ADC, digital filters, and PLL, drawing only 28 µA from the analog supply and 2 µA from the digital core supply. While not zero, this represents >99% reduction versus active playback mode. The analog signal path (e.g., MIC1 → LINE_OUT) remains functional with 330-Ω switch resistance, enabling voice-trigger applications without waking the host processor. This behavior is measured and specified in the Electrical Characteristics section of the TLV320AIC3106 datasheet.
