Texas Instruments TLV320AIC3107IRSBR

Overview

TLV320AIC3107IRSBR from Texas Instruments is a low-power stereo audio codec with integrated mono Class-D speaker amplifier, stereo headphone drivers, and dual line outputs. It delivers 97-dBA SNR DAC performance, 92-dBA SNR ADC performance, ±59.5 dB programmable PGA gain in 0.5-dB steps, and supports 8–96 kHz sample rates across I²S, left/right-justified, DSP, and TDM audio serial formats - deployed in cellular handsets and portable media players.

For engineers reviewing the TLV320AIC3107IRSBR datasheet, TLV320AIC3107IRSBR pinout, TLV320AIC3107IRSBR application, or TLV320AIC3107IRSBR equivalent, key selection criteria include its 40-pin WQFN package with exposed thermal pad, integrated AGC with 8-ms to 1.4-s attack and 50-ms to 22.4-s decay tuning, ultra-low 15-mW stereo 48-kHz playback power, and flexible analog input configuration (6 single-ended or 3 fully differential channels).

Technical Context

The TLV320AIC3107IRSBR integrates three independent analog signal paths: a stereo ADC path with programmable microphone bias, digital AGC, and decimation filtering; a stereo DAC path with 3D/bass/treble/EQ/de-emphasis processing; and a mono Class-D speaker driver capable of 1 W into 8 Ω. Its modular power control enables selective block shutdown, achieving 28 μA deep-sleep current with headset detection active.

It features a highly configurable audio serial interface supporting master/slave modes, programmable PLL for MCLK-to-audio-rate synthesis (512 kHz–50 MHz input), and dual-domain voltage supplies: analog (2.7–3.6 V), digital core (1.525–1.95 V), I/O (1.1–3.6 V), and speaker amplifier (2.7–5.5 V). The device implements passive analog bypass via SWINP/SWOUTP and SWINM/SWOUTM switches with <1 Ω rDS(on).

FAQ

What is the maximum supported audio sample rate for TLV320AIC3107IRSBR?

The TLV320AIC3107IRSBR supports audio sample rates from 8 kHz to 96 kHz for both ADC and DAC paths. This range accommodates narrowband telephony (8 kHz), wideband VoIP (16 kHz), CD-quality (44.1 kHz), and high-resolution playback (96 kHz), with all rates achievable using the integrated programmable PLL and standard MCLK inputs.

Does TLV320AIC3107IRSBR include automatic gain control (AGC) functionality?

Yes, TLV320AIC3107IRSBR includes a fully programmable AGC block in the ADC path. It supports adjustable attack times from 8 ms to 1.408 s and decay times from 50 ms to 22.4 s, enabling optimization for voice calls, music recording, or environmental monitoring. AGC operates independently of digital signal processing and can be enabled/disabled per channel.

What are the power supply requirements for TLV320AIC3107IRSBR?

TLV320AIC3107IRSBR requires four independent supply domains: analog (2.7–3.6 V), digital core (1.525–1.95 V), I/O (1.1–3.6 V), and speaker amplifier (2.7–5.5 V). Each domain has dedicated supply pins (e.g., AVDD_ADC, DVDD, IOVDD, SPVDD) and corresponding ground returns to ensure signal integrity and minimize noise coupling between functional blocks.

Can TLV320AIC3107IRSBR operate in analog bypass mode?

Yes, TLV320AIC3107IRSBR supports analog signal pass-through mode using its internal SWINP/SWOUTP and SWINM/SWOUTM switches. In this mode, signals like LINE1L can route directly to LEFT_LOP with <330 Ω on-resistance and no digital processing, reducing total system power to under 30 μA while maintaining analog connectivity - ideal for always-on headset detection or low-power wake-up paths.

What package type is used for TLV320AIC3107IRSBR?

TLV320AIC3107IRSBR uses a 5.15 mm × 5.15 mm, 40-pin WQFN package with an exposed thermal pad (RSB suffix). This RoHS-compliant package provides excellent thermal performance (θJA = 30.7°C/W) and is optimized for automated assembly in high-density portable PCB layouts.
