Product details
Overview
TLV320AIC3106 from Texas Instruments is a low-power stereo audio CODEC integrating dual 24-bit DACs (102-dBA SNR), dual 24-bit ADCs (92-dBA SNR), programmable AGC, stereo headphone amplifier, and seven configurable analog outputs - designed for portable battery-powered audio/telephony systems requiring high-fidelity playback and noise-robust recording at 8–96 kHz sampling rates.
For engineers reviewing the TLV320AIC3106 datasheet, TLV320AIC3106 pinout, TLV320AIC3106 application, or TLV320AIC3106 equivalent, this device supports I²S/TDM/DSP audio serial interfaces, SPI/I²C control, ultralow-power analog bypass mode, concurrent analog/digital microphone inputs, and flexible clock generation via integrated PLL - critical for compact, power-constrained mobile designs.
Technical Context
The TLV320AIC3106 implements independent stereo DAC and ADC signal paths with fully programmable digital filtering (3D, bass/treble/EQ/de-emphasis), programmable input/output gain stages, and automatic gain control with tunable attack (8 ms–1.4 s) and decay (0.05–22.4 s) timing. Its analog front-end supports ten input pins configurable in single-ended or differential modes, including 3-state capability for floating inputs.
Dual power domains isolate analog (2.7–3.6 V) and digital core (1.65–1.95 V) supplies, while extensive modular power control enables 15-mW stereo 48-kHz playback. The integrated PLL accepts MCLK inputs from 512 kHz to 50 MHz - supporting standard audio rates without external crystal oscillators.

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 input and mono line output; identical DAC/ADC specs and power profile. | Suitable for cost-sensitive designs omitting third mic or mono output - e.g., basic smartphones without secondary mic array. | Select TLV320AIC3104 when system requires only two stereo inputs and no mono line-out functionality. |
| TLV320AIC3107 | Includes integrated mono Class-D amplifier (1.5 W into 8 Ω); same 7-output structure but replaces one line driver with Class-D stage. | Targeted at speakerphone or portable speaker applications needing local amplification - not suitable for pure headphone/line-out use cases. | Choose TLV320AIC3107 only if mono speaker drive capability is required and thermal derating for Class-D operation is acceptable. |
Compared with TLV320AIC3104 and TLV320AIC3107, the TLV320AIC3106 uniquely balances 10-input flexibility, 7-output versatility, and ultralow-power analog bypass - making it optimal for dual-mic telephony and multi-source recording where pin count and feature completeness are critical.

FAQ
What is the minimum analog supply voltage required for TLV320AIC3106 operation?
The TLV320AIC3106 requires an analog supply voltage between 2.7 V and 3.6 V for both AVDD_DAC and DRVDD rails. Operation below 2.7 V is outside specification and may cause undefined behavior in DAC/ADC conversion, headphone driver output, or internal reference stability. Always maintain AVDD_DAC and DRVDD within this range with proper decoupling.
Does TLV320AIC3106 support I²S master mode for audio data transmission?
Yes, TLV320AIC3106 supports I²S master mode on its audio serial data bus. In master mode, the device generates BCLK and WCLK signals using its internal PLL, allowing it to drive external DACs, ADCs, or digital audio processors without requiring an external clock source - confirmed in Section 8.6 of the SLAS509G datasheet.
Can TLV320AIC3106 simultaneously process analog and digital microphone inputs?
Yes, TLV320AIC3106 supports concurrent analog and digital microphone inputs. It provides dedicated analog input pins (MIC1L/R, MIC2L/R, MIC3L/R) and uses GPIO1/GPIO2 as digital microphone clock/data interfaces - enabling hybrid capture scenarios such as analog MEMS + PDM mic without external logic.
What is the maximum sampling rate supported by TLV320AIC3106 DAC and ADC?
The TLV320AIC3106 supports sampling rates from 8 kHz to 96 kHz for both DAC and ADC paths. This includes standard telephony (8 kHz), VoIP (16 kHz), CD-quality (44.1 kHz), and high-resolution audio (48 kHz, 96 kHz) - verified in Sections 1 and 5 of the SLAS509G datasheet.
How does the ultralow-power analog bypass mode function in TLV320AIC3106?
In ultralow-power analog bypass mode, TLV320AIC3106 powers down most internal circuitry while maintaining analog signal path continuity - e.g., MIC1/LINE1 to LINE_OUT - with typical switch resistance of 330 Ω. This mode draws only 28 μA, enabling always-on headset detection or passive audio routing without CPU intervention.
