Product details
Overview
6PAIC3106IRGZRQ1 from Texas Instruments is an AEC-Q100 Grade 3 qualified stereo audio codec IC for automotive infotainment systems, integrating stereo 102-dBA DAC, 92-dBA ADC, ten programmable analog inputs (single-ended or differential), seven output drivers including stereo headphone and line outputs, and ultralow-power 15-mW 48-kHz playback - deployed in cluster and head unit audio subsystems.
For engineers reviewing the 6PAIC3106IRGZRQ1 datasheet, 6PAIC3106IRGZRQ1 pinout, 6PAIC3106IRGZRQ1 application, or 6PAIC3106IRGZRQ1 equivalent, this page delivers verified technical context, automotive-grade power/performance trade-offs, I²C/SPI control bus selection, and confirmed pin-level interface roles for system integration into eCall, telematics, and car audio platforms.
Technical Context
The 6PAIC3106IRGZRQ1 implements a dual-path audio signal chain with independent programmable gain amplifiers (up to 59.5 dB) and digital AGC (attack: 8 ms–1408 ms; decay: 0.05 s–22.4 s) on the ADC side, and configurable 3D/bass/treble/EQ/de-emphasis filtering on the DAC path. Its PLL supports flexible clock generation from 512 kHz to 50 MHz MCLK, enabling precise 8–96 kHz sampling rate synthesis without external crystal.
It features three fully differential and four high-power output drivers, supporting capacitorless 16-Ω stereo headphone drive and differential line outputs (10 kΩ load), with analog pass-through mode (rDS(ON) = 330 Ω) for low-latency signal routing - all under triple-supply operation: 2.7–3.6 V analog, 1.65–1.95 V digital core, and 1.1–3.6 V I/O.

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-Q1 | 6-input / 6-output configuration; lacks MONO_LOP/MONO_LOM and one LINE input pair | Insufficient I/O count for multi-mic eCall + dual-line-out telematics; not suitable for 3-input microphone arrays | Select only when system requires fewer analog channels and lower pin count; RGZ package identical |
| PCM3168A-Q1 | 8-channel ADC/DAC (not stereo-focused); no integrated headphone amp; higher power (25 mW typical) | Targeted at multichannel amplifier interfaces, not head unit cluster audio; requires external headphone driver | Choose for 8-channel recording/playback in amplifier control units; avoid for space-constrained cluster designs |
Compared with TLV320AIC3104-Q1 and PCM3168A-Q1, the 6PAIC3106IRGZRQ1 uniquely balances 10-input flexibility, integrated 16-Ω headphone drive, and 15-mW efficiency - making it the only option qualified for direct replacement in AEC-Q100 Grade 3 cluster audio subsystems requiring full-feature stereo codec functionality.

FAQ
What is the operating temperature range for the 6PAIC3106IRGZRQ1?
The 6PAIC3106IRGZRQ1 is qualified for automotive Grade 3 operation, with a guaranteed ambient operating temperature range of –40°C to +85°C. This rating is validated per AEC-Q100 standards and applies across all electrical specifications in the datasheet, including SNR, THD+N, and power consumption metrics - no derating required within this range.
Does the 6PAIC3106IRGZRQ1 support both I²C and SPI control interfaces?
Yes, the 6PAIC3106IRGZRQ1 supports both I²C and SPI control buses. The SELECT pin (Pin 43) determines protocol selection: logic low configures I²C (SCL/SDA on Pins 1/2), logic high enables SPI (MFP0–MFP3 used as CS/SCLK/MISO/MOSI). Both interfaces provide full register access for audio path configuration and power management.
How many analog inputs does the 6PAIC3106IRGZRQ1 support, and what configurations are available?
The 6PAIC3106IRGZRQ1 supports ten analog input pins: LINE1LP/LM/RP/RM, LINE2LP/LM/RP/RM, MIC3L, and MIC3R. Each can be configured as single-ended or fully differential via register settings. Input mixers and 3-state capability allow dynamic reconfiguration without external switching, supporting up to three independent microphone channels or six line-level sources.
What is the minimum power consumption of the 6PAIC3106IRGZRQ1 in standby mode?
In ultralow-power standby with headset detection enabled and all blocks powered down, the 6PAIC3106IRGZRQ1 draws just 28 µA from the analog supply (IDRVDD + IAVDD_DAC) and 2 µA from the digital core supply (IDVDD). This mode retains mic bias and interrupt capability - critical for eCall wake-up functionality without waking the host MCU.
Is the 6PAIC3106IRGZRQ1 pin-compatible with other devices in the TLV320AIC31xx-Q1 family?
No, the 6PAIC3106IRGZRQ1 is not pin-compatible with TLV320AIC3104-Q1 or TLV320AIC3110-Q1. While all use the same 48-pin VQFN (RGZ) package, pin functions differ significantly - for example, TLV320AIC3104-Q1 lacks MONO_LOP/MONO_LOM and has different GPIO mappings. PCB layout must be designed specifically for 6PAIC3106IRGZRQ1.
