Product details
Overview
TLV320AIC3107IYZFT from Texas Instruments is a low-power stereo audio codec with integrated mono Class-D speaker amplifier, stereo headphone amplifier, and programmable analog/digital signal processing. It delivers 97-dBA SNR DAC performance, 92-dBA SNR ADC performance, ±59.5 dB PGA gain in 0.5-dB steps, and supports 8–96 kHz sample rates across I²S, left/right-justified, DSP, and TDM audio serial interfaces. It targets portable battery-powered audio systems requiring high fidelity and ultra-low power.
For engineers reviewing the TLV320AIC3107IYZFT datasheet, TLV320AIC3107IYZFT pinout, TLV320AIC3107IYZFT application, or TLV320AIC3107IYZFT equivalent, key selection criteria include its integrated Class-D speaker driver (1 W into 8 Ω), dual-channel AGC with 8-ms to 1.4-s attack and 50-ms to 22.4-s decay, programmable microphone bias (2.0–2.7 V), and flexible power domain partitioning (1.525–1.95 V core, 2.7–3.6 V analog, 2.7–5.5 V speaker supply).
Technical Context
The TLV320AIC3107IYZFT implements a fully configurable audio signal chain: seven analog inputs (programmable as six single-ended or three differential) feed into stereo ADCs with digital decimation filtering and AGC; stereo DACs drive headphone/line outputs with programmable volume, 3D/bass/treble/EQ/de-emphasis effects, and common-mode voltage options (1.35–1.8 V); a dedicated mono Class-D BTL amplifier drives 8 Ω speakers at up to 1 W.
Its digital architecture includes an I²C control bus, audio serial data interface supporting master/slave modes, and a highly programmable PLL accepting MCLK inputs from 512 kHz to 50 MHz to generate precise audio clocks for all standard sample rates. Power management enables 15-mW stereo 48-kHz playback (3.3-V analog supply) and ultra-low-power analog pass-through mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar stereo audio codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV320AIC3106IRGZR | Lacks integrated Class-D speaker amplifier; same ADC/DAC performance and pinout-compatible QFN package | Requires external speaker driver; better suited for designs needing only headphone/line outputs | Select when speaker amplification is handled externally and PCB layout must match TLV320AIC3107 footprint |
| WM8960GEFL/V | Higher 98-dBA DAC SNR; no integrated Class-D; uses different I²C register map and requires separate mic bias circuit | Superior line-out fidelity but adds design complexity for mic bias and speaker drive | Select when maximum DAC SNR is critical and system already includes speaker amp/mic bias solutions |
Compared with TLV320AIC3107IYZFT, TLV320AIC3106IRGZR offers identical audio quality and control interface but omits the Class-D amplifier-reducing power and cost where speaker output is unnecessary. WM8960GEFL/V provides marginally higher DAC SNR but increases BOM count and firmware effort due to missing integrated features.

FAQ
What is the maximum output power of the Class-D amplifier in TLV320AIC3107IYZFT?
The TLV320AIC3107IYZFT Class-D amplifier delivers 1 W of continuous output power into an 8-Ω load under typical conditions (SPVDD = 5 V, 1-kHz sine wave). This is achieved in BTL (bridge-tied-load) configuration using the SPOP and SPOM differential outputs, enabling loudspeaker drive without external amplification stages.
Does TLV320AIC3107IYZFT support differential microphone inputs?
Yes, TLV320AIC3107IYZFT supports differential microphone inputs: its seven analog input pins can be configured as three fully differential pairs (e.g., LINE1LP/LINE1LM, LINE2LP/LINE2LM, MIC3L/MIC3R), providing 92-dBA SNR in differential mode and improved common-mode noise rejection over single-ended operation.
What are the supported audio serial interface formats for TLV320AIC3107IYZFT?
TLV320AIC3107IYZFT supports I²S, left-justified, right-justified, and TDM audio serial data formats on its DIN/DOUT/BCLK/WCLK interface. Both master and slave modes are implemented, allowing flexible integration with DSPs, microcontrollers, or baseband processors regardless of clock source ownership.
Can TLV320AIC3107IYZFT operate in ultra-low-power analog pass-through mode?
Yes, TLV320AIC3107IYZFT supports analog pass-through mode where LINE1/LINE2 inputs are directly switched to LEFT_LOP/RIGHT_LOP outputs with <330-Ω rDS(on), while powering down ADC, DAC, and digital core. In this state, total current draw drops to 28 μA (DRVDD+AVDD_DAC), ideal for always-on headset detection or standby audio routing.
What is the programmable range of the microphone bias voltage in TLV320AIC3107IYZFT?
The TLV320AIC3107IYZFT provides programmable microphone bias voltage with three settings: 2.0 V, 2.5 V, or DRVDD (2.7–3.6 V). The 2.5-V setting delivers up to 4 mA, sufficient for most electret condenser microphones, and is factory-trimmed to ±3% accuracy across temperature and supply variations.
