Product details
Overview
6PAIC3104TRHBRQ1 from Texas Instruments is an AEC-Q100 Grade 2 automotive stereo audio codec with integrated 102-dBA DAC, 92-dBA ADC, six analog inputs (including differential microphone/line pairs), six output drivers (four high-power headphone + two differential line), and programmable AGC, EQ, and PLL - deployed in infotainment head units and digital instrument clusters for eCall and telematics.
For engineers reviewing the 6PAIC3104TRHBRQ1 datasheet, 6PAIC3104TRHBRQ1 pinout, 6PAIC3104TRHBRQ1 application, or 6PAIC3104TRHBRQ1 equivalent, this page delivers verified technical context, validated pin functions, confirmed automotive-grade power and SNR specs, and real-world implementation constraints for cluster audio subsystems.
Technical Context
The 6PAIC3104TRHBRQ1 implements delta-sigma modulation in both DAC (8–96 kHz) and ADC (8–96 kHz) paths, with independent programmable gain amplifiers (up to 59.5 dB) on all analog inputs and automatic gain control featuring tunable attack (8 ms–1.4 s) and decay (0.05–22.4 s). Its digital audio processor supports I2S, left/right-justified, DSP, and TDM serial formats via a configurable audio data bus.
Power architecture separates analog (AVDD/DRVDD: 2.7–3.6 V), digital core (DVDD: 1.525–1.95 V), and I/O (IOVDD: 1.1–3.6 V) domains, enabling ultralow-power analog passthrough mode where most circuitry powers down while maintaining signal path integrity - critical for eCall wake-on-voice scenarios.
Key Specifications

Does the 6PAIC3104TRHBRQ1 support differential microphone inputs?
Yes, the 6PAIC3104TRHBRQ1 supports two fully differential microphone input pairs: MIC1LP/MIC1LM and MIC1RP/MIC1RM (Pins 10/11 and 12/13). Each pair accepts balanced signals with 92-dBA SNR and programmable PGA gain up to 59.5 dB, enabling noise-canceling beamforming for eCall voice capture.
Can the 6PAIC3104TRHBRQ1 drive 16-Ω headphones directly without external capacitors?
Yes, the 6PAIC3104TRHBRQ1 supports capless (fully differential) headphone output configuration using HPLOUT/HPLCOM and HPROUT/HPRCOM pins. In this mode, it delivers up to 30 mW into 16-Ω loads with 94-dB SNR and <0.028% THD+N at 20 mW - eliminating DC-blocking capacitors and saving board space.
What audio serial interface modes does the 6PAIC3104TRHBRQ1 support?
The 6PAIC3104TRHBRQ1 supports I2S, left-justified, right-justified, and TDM audio serial data formats on its configurable audio bus. Mode selection is register-controlled via I2C, allowing dynamic reconfiguration between stereo and multi-channel use cases without hardware changes.
Is the 6PAIC3104TRHBRQ1 pin-compatible with other devices in the TLV320AIC31xx-Q1 family?
No, the 6PAIC3104TRHBRQ1 is not pin-compatible with TLV320AIC3106-Q1 or TLV320AIC3110-Q1. While all share the VQFN-32 package, pin assignments differ significantly - especially for input/output channels and bias functions - requiring unique PCB layouts for each variant.
