6PAIC3109TWRHMRQ1

Overview

The Texas Instruments 6PAIC3109TWRHMRQ1 is an automotive-grade, low-power mono audio codec designed for high-fidelity sound reproduction. It features a 16-bit resolution and supports sampling rates up to 96 kHz. The device integrates a single DAC output and communicates via an I2C interface. It operates within a supply voltage range of 1.8 V to 3.3 V and is qualified under the AEC-Q100 standard. The component is housed in a compact VQFN-32 package, suitable for surface mount technology, and functions reliably across an extended temperature range from -40°C to +105°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability
• Low-power mono audio codec architecture optimized for efficiency
• Integrated digital-to-analog conversion with 16-bit precision

Applications

• Automotive infotainment systems requiring mono audio playback
• Vehicle notification and alert sound generation circuits
• Hands-free communication subsystems in automotive environments

Procurement Notes

Verify the complete part number including the suffix TWRHMRQ1 to ensure correct packaging and automotive grade specification. Confirm that the intended application environment falls within the specified operating temperature range of -40°C to +105°C. Ensure the system power supply aligns with the 1.8 V to 3.3 V operational limits defined in the datasheet.

Selection Notes

Select this component when a mono audio output is sufficient for the application design. The 16-bit resolution and 96 kHz sampling rate provide adequate fidelity for voice and basic music playback. Consider the VQFN-32 package size if board space is constrained. Verify compatibility with the host controller's I2C interface capabilities before integration.

Part Context

This part belongs to the TLV320AIC31xx series of low-power audio codecs manufactured by Texas Instruments. The series is engineered for portable and automotive applications where power consumption and audio quality are critical. The specific model indicates a mono configuration with integrated DAC functionality, distinguishing it from stereo variants or ADC-focused models within the same family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult the official Texas Instruments website or authorized distributor databases for current cross-reference information. Any replacement must match the AEC-Q100 qualification, pinout, and functional specifications.
