Product details
Overview
6PAIC3109TWRHMRQ1 from Texas Instruments is an AEC-Q100 Grade 2 automotive mono audio codec with integrated 102-dBA DAC, 92-dBA ADC, programmable PGA (0–59.5 dB), and dual headphone/line output drivers in a wettable-flank VQFN-32 package. It supports 8–96 kHz sample rates, I²C control, and operates from 2.7–3.6 V analog supplies for eCall systems and telematics control units.
For engineers reviewing the 6PAIC3109TWRHMRQ1 datasheet, 6PAIC3109TWRHMRQ1 pinout, 6PAIC3109TWRHMRQ1 application, or 6PAIC3109TWRHMRQ1 equivalent, key selection criteria include its wettable-flank packaging for automotive solder-joint inspection, ultra-low 14-mW 48-kHz playback power, differential input/output flexibility, and AEC-Q100 qualification for –40°C to +105°C operation.
Technical Context
The 6PAIC3109TWRHMRQ1 implements delta-sigma modulation for both ADC and DAC paths, with digital decimation/interpolation filters supporting 8–96 kHz sampling. Its fully programmable PLL enables flexible clock generation from MCLK, eliminating external crystal requirements in many automotive audio interfaces.
Signal routing is managed via register-configurable analog mixers (MIX) and multiplexers (MUX), allowing dynamic path selection between MIC/LINE inputs, PGA stages, AGC, and output drivers-including HPOUT/HPCOM for headphone and LEFT_LOP/LEFT_LOM/RIGHT_LOP/RIGHT_LOM for line outputs-without hardware reconfiguration.

FAQ
What is the primary function of the 6PAIC3109TWRHMRQ1 in automotive systems?
The 6PAIC3109TWRHMRQ1 serves as a mono audio codec integrating ADC, DAC, programmable PGA, AGC, and headphone/line drivers. In automotive systems, it enables voice capture and playback for eCall, telematics, and head unit interfaces. Its AEC-Q100 Grade 2 qualification, wettable-flank package, and 14-mW 48-kHz playback make it purpose-built for reliable, low-power voice communication in vehicles. The 6PAIC3109TWRHMRQ1 supports differential microphone inputs and flexible I²S/DSP audio interfaces to match common SoC architectures.
Does the 6PAIC3109TWRHMRQ1 support differential audio inputs and outputs?
Yes, the 6PAIC3109TWRHMRQ1 supports two differential microphone/line inputs (MIC1P/MIC1M and MIC2P/MIC2M) and fully differential headphone (HPOUT/HPCOM) and line outputs (LEFT_LOP/LEFT_LOM, RIGHT_LOP/RIGHT_LOM). Each differential pair can be configured independently via register settings. The device also supports single-ended configurations for all inputs and outputs, providing design flexibility. This capability is confirmed in the functional block diagram and pin functions table of the TLV320AIC3109-Q1 datasheet, and applies directly to the 6PAIC3109TWRHMRQ1 variant.
What power supply voltages does the 6PAIC3109TWRHMRQ1 require?
The 6PAIC3109TWRHMRQ1 requires three independent supply domains: analog (AVDD/DRVDD) at 2.7–3.6 V, digital core (DVDD) at 1.525–1.95 V, and digital I/O (IOVDD) at 1.1–3.6 V. AVDD powers the DAC and analog circuitry; DRVDD supplies the ADC and output drivers; DVDD powers the digital core; IOVDD sets logic thresholds for I²C and audio serial interface pins. These separate rails minimize noise coupling and enable optimized power domain partitioning in automotive PCB layouts. All specifications assume these ranges, as defined in Section 6.3 of the TLV320AIC3109-Q1 datasheet.
How does the wettable-flank package of the 6PAIC3109TWRHMRQ1 benefit automotive manufacturing?
The wettable-flank VQFN-32 package of the 6PAIC3109TWRHMRQ1 enables automated optical inspection (AOI) of solder joint quality along the vertical sidewalls of the package-critical for zero-defect automotive production. Unlike standard VQFN packages, wettable flanks allow machine vision systems to verify fillet formation and solder coverage on all perimeter leads, improving process yield and field reliability. This feature is explicitly called out in the "Released 6PAIC3109TWRHMRQ1 (wettable-flank package option) to production" line of the datasheet revision history and is a mandatory requirement for many Tier 1 automotive suppliers.
Can the 6PAIC3109TWRHMRQ1 operate without an external crystal?
Yes, the 6PAIC3109TWRHMRQ1 can operate without an external crystal thanks to its fully programmable PLL, which synthesizes required audio clocks (e.g., 12.288 MHz for 48 kHz sampling) from a single MCLK input ranging from 1 MHz to 50 MHz. This eliminates the need for precision crystals or oscillators in many automotive audio designs, reducing BOM cost and board space. The PLL configuration is register-controlled via I²C, and its operation is validated across the full temperature range (–40°C to +105°C) per AEC-Q100 requirements. This capability is documented in Section 7.3.4 of the TLV320AIC3109-Q1 datasheet and applies to the 6PAIC3109TWRHMRQ1.
