6PAIC3109TRHBRQ1

Overview

The Texas Instruments 6PAIC3109TRHBRQ1 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 with an I2C digital interface for system control. It operates on dual power supplies of 1.8 V and 3.3 V, ensuring compatibility with various logic levels. The component is qualified under AEC-Q100 standards and functions reliably within an extended temperature range from -40°C to +105°C. It is housed in a compact VQFN-32 package suitable for surface-mount assembly.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability
• Low-power mono audio codec architecture optimized for efficiency
• Integrated 16-bit digital-to-analog converter with high fidelity
• Flexible I2C serial interface for simplified system integration

Applications

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

Procurement Notes

Verify the specific suffix TRHB against official Texas Instruments documentation to confirm tape-and-reel packaging and exact pinout configuration. Ensure the procurement channel provides valid traceability for AEC-Q100 certified components. Cross-reference the manufacturer part number with authorized distributor catalogs to prevent substitution errors. Confirm that the delivered units match the specified VQFN-32 package dimensions and thermal characteristics required for the target application design.

Selection Notes

Select this component when a mono audio output is sufficient for the application, as it lacks integrated ADC channels. Compare power consumption metrics against other members of the TLV320DAC310x family if stereo capability is not required. Verify that the 1.8 V and 3.3 V supply rails are available in the target system design. Consider the VQFN-32 package size constraints during PCB layout planning to ensure adequate thermal dissipation and mechanical stability.

Part Context

This part belongs to the TLV320DAC310x series of low-power audio codecs from Texas Instruments. The series includes variants such as the 6PAIC3109 and 6PA3100, differing primarily in channel count and performance specifications. The 6PAIC3109TRHBRQ1 specifically targets cost-sensitive automotive applications where mono playback is adequate. It shares the same core technology and interface protocols as its stereo counterparts but offers a simplified solution for single-channel requirements.

Replacement Considerations

Direct replacements within the same family include the 6PAIC3109IRHBRQ1, which may differ only in temperature grade or packaging variant. Verify pin-to-pin compatibility before substituting. Other series members like the 6PA3100 offer stereo outputs but require different software configuration. Always consult the latest datasheet revision notes to ensure functional equivalence regarding register maps and electrical characteristics.
